If you find out the answer, tell me please. Lately, I realized that people are becoming empty and selfish. They care too much about phisycal appearance and less about your good behaviors. So, even when you are very kind to them, for some, it doesn´t matter anything. So, you can find someone to talk a bit. However, to consider as a true friend, and realize in the same way that you are considered as a true friend, is too rare you find out (at least for me).
True friendship is an easy concept to me: Two or more people who care about each other, keep in touch regularly and are always willing to help each other. Besides that, all of them must having respect, humility and honesty between each other.
