In one sentence, describe what the following article is about:

It’s never helpful to tell someone to stop crying or that whatever they are crying about isn’t worth their tears. Crying lets a person feel better. Emotions when vented are better than if they are stored inside because bottled up emotions lead to mental illnesses like depression. If someone is crying, let them cry. Never say things like, "Don't cry" or "This is such a small thing, why are you crying?" They are sharing a vulnerable moment with you, so allow them to express what needs to be expressed without telling them how to feel. You might feel awkward or uncomfortable around someone who’s crying. Remember that your role is to offer support in a way that’s helpful to them, and the focus is ultimately not on you. They might want you to stay and listen or they may want some space and alone time. Don’t assume you know what they want because you don’t. Asking what they want and need puts the other person in control and gives you the opportunity to listen and respond. Whatever they ask for or need, respect what they say.  Ask, “What can I do to help?” or “How can I support you?” If they ask that you leave, leave. Refrain from saying things like "But you need me to help you!", rather just say "Okay, fine but if you need something, call or text me." People need space sometimes. You shouldn’t feel like you’re in a rush or need to go do something. Part of being supportive is being there and giving your time for the person. If you’re there to comfort them, give them the time that they need. Your presence alone can be comforting, so sticking around and making sure they are capable of getting on with their day or getting further help can be what they need most. Don’t stop for a few moments then get on with your day. Stay with them and let them know you will stay if they need you. Even if you have work to do, giving a few mins extra won't hurt. If you know your friend likes hugs, give them a hug. However, if they tend to be more physically reserved, you may wish to pat them on the back or perhaps not touch them at all. If you’re helping a stranger, it’s best to ask if they want physical touch. If you’re in doubt, ask if they’d like a hug or for you to hold them. If they don't want physical touch, don't do it. Ask, "Mind if I hug you"? Your friends or family may want physical touch more than strangers, so make sure you don't make the person more uncomfortable.
Let them cry. Ask what they need. Give them time. Give some affection if wanted.
