What is a one-sentence summary of the following article?
If you are not interested, you should let the person know you have no intentions of carrying on a romantic relationship with him or her, but be as nice as possible about it. Avoid making a blunt statement such as "I am not interested in you.” Phrasing your lack of interest in this way would come across as rude and inconsiderate. Try saying something like, “This is hard for me to say, but I have to be honest with you. I have really enjoyed spending time with you, but I don’t think that we are a good match. You deserve to meet someone who shares your interests and goals and I just do not think that I am that person. But I wish you all the best and I have enjoyed getting to know you.” If you do not feel any chemistry but suspect that the two of you may become friends, try making that suggestion. If you do this, be absolutely clear that all you want is friendship. It is possible that this may not be an option if the other person is attracted to you. However if the other person shares your idea, you might have found a great new friend out of a bad date.  Try saying something like, “Even thought we were not a match, I had a good time getting to know you. Do you think we could be friends?” Keep in mind that this strategy can backfire as well, so be careful about using it. Some people may feel just as rejected if you suggest that the two of you become friends. It is also possible that your lack of chemistry may mean that you do not even have enough in common to become friends. If the other person is interested in a second date, you should politely decline either after the first date or later on. You do not need to provide a concrete reason. Avoid being non-committal and do not say things like “maybe we can meet again some time.” Although you may be reluctant to hurt someone's feelings, it is sometimes necessary to do so in order to find what you are looking for. Try saying something like, “It was great to meet you and to get to know you, but I don’t think that we should go on another date. I think you are a great person, but I do not think we are a match. I wish you the best of luck thought and I hope that you find the right guy/girl for you.”
Say that you are not interested in a kind way. Suggest the two of you become friends. Reject the possibility of future dates.
