Article: Introduce yourself by name. Unless any further info is needed immediately, leave everything else unmentioned. Remember: unlike a job interview, there’s no rush here to advertise all of your best qualities right up front. Allow the other person to learn about you organically, through a give-and-take conversation. If the situation calls for it, add a relevant fact to further identify yourself when you first meet, like:  “Hi, I’m ___, the birthday boy’s best friend.” “Hi, I’m ___. Your daughter’s in the same class as my son.” “Hi, I’m ___. Your brother and I work in the same office.” Impress people by not worrying about whether or not you’re impressing them. Stay true to yourself instead. Of course, we all have different sides to ourselves, so be the “you” that’s most appropriate to the situation. For example:  If you’re meeting a new study-partner, keep the focus on your schoolwork and school-life in general. If you’re meeting people for the first time after moving to a new area, play up your role as the recent transplant experiencing culture shock. If a mutual friend has invited you (as well as a bunch of other friends of theirs who are die-hard fans) to a sports game that you’re unfamiliar with, stay true to your outsider status instead of pretending to be an expert. Feel free to talk about things in your life that you’re proud of if the conversation turns that way, but keep it in check. Earn the other person’s respect with your actions in the here and now instead of demanding it by talking about all the things you’re achieved in the past. Prove to them that you’re confident of your own self-worth and don’t need other people’s admiration to bolster it.  If the conversation turns to your job, tell them where you work and maybe a very general description of what you do, while leaving any fancy job titles unmentioned.  If they recognize you as an All-State athlete, play down your own accomplishment and credit your team and/or coach for making it at all possible.  If someone else mentions how you rushed into a burning building last week to save a pet cat, show or feign embarrassment and then switch topics rather than gloat over your own bravery. If you find yourself uncomfortable for whatever reason, mention the fact lightly. Show your self-confidence by freely admitting that you’re not perfect. Make the other person more comfortable by showing them that they’re free to do the same. This way you’re more likely to take command of the situation instead of being at its mercy.  If you have trouble remembering names (especially if you’re being introduced to many people at once), fess up and apologize that you’ll probably forget them by the end of the night. If they know this, they’re more likely to repeat their names for your benefit later on. If you’re uncomfortable at large parties or gatherings, say as much if it’s crimping your style. Let the other person know that your best self is better seen in more intimate settings. If you’re on a first date and haven't dated for a while (or at all), share this with your date. Assure them that any odd behavior on your part is due to a lack of experience, and not a reflection on them personally. Build a real conversation between yourselves instead of just talking at each other. When they tell you something, respond directly to their comment. If you have a personal story that’s relevant to what they’ve said, be sure to tell it in a way that clearly shows your story is a response, and not just an opportunity to switch subjects and talk about yourself. Ask follow-up questions when they tell their own stories to show that they have your interest.  "I never thought of it that way. I'll have to watch that movie again with that fan theory in mind." "That sounds like a pretty stressful vacation. Would you go back there again if you had the chance?" "The same thing happened to me once, or almost the same thing. Only in my case ..." Ensure that you’ll make a good impression by persuading them that they’ve done the same with you. Don’t undermine your own introduction by judging theirs unfairly. Assume they mean the best, even when they make a faux-pas. Always give people the benefit of the doubt until they give you a very real reason not to.
Question: What is a summary of what this article is about?
Keep your introduction simple. Be confident. Refrain from bragging. Share your anxieties or discomforts. Listen. Think the best about the other person.

If you are really having trouble moving on it can be helpful to deal with these feelings in a professional setting. A trained therapist will be able to listen to your perspective of what went wrong in the friendship and help you learn from mistakes. When friends are the problem, sometimes turning to family can be a safe solution. If you can, try to call someone you think has gone through similar friendship breakups in the past. Perhaps a parent or grandparent with more life experience, though any family member can be an enormous comfort. Reach out to people who don't know the friend or friends you are no longer hanging out with. They can listen to how you feel and offer an objective perspective on the situation. Let them know how much you appreciate their support. Remember that even though you may have lost a friend, you are still not completely friendless. Mutual friends may not be the best people to reach out to if you feel like you really need to process the loss of the friendship. This puts your shared friends in an awkward position. You'll also run the risk of alienating more people if you are perceived as trying to get people to take sides. That said, you can still reach out to these friends for companionship. It can be a nice reminder that you still have people that care about you.  Avoid mentioning the friend that no longer wants to hangout with you. Try to focus on the things you still have in common with your current friends. It can be very emotional when a friend says they do not want to hangout with you anymore. Avoid the temptation to talk badly about them or tarnish their reputation in any way. When the emotions die down you may both realize that the friendship is actually salvageable. It may even come back together stronger after a disagreement of this magnitude. You don't want to make the situation any worse or lower any chances of the friendship being mended because you bad mouthed someone behind their back.
