If that friend doesn't laugh at you behind your back. If he doesn't like your behaviour he can tell you directly and not to others. Someone who will be there when you need the most. Someone who has time for you when you are in trouble. Someone who encourages you when you don't even believe in yourself that you can do it. Someone who will tell you to quit when you are in wrong track. Someone you don't feel awkward and you are relieved when you are with him. And you can discuss everything without hesitating. For me they are my second family. I am relieved when I'm with her. The best thing I like about her is we can talk everything and even when we have difference of opinion, we respect each others thought. I am lucky to have you in my life.
