How do you know if your friends are for real?

I don't test my friendship. I make friends randomly and keep on continuing them. For precaution i select 2-3 friends who r close to me & tell my secrets. You could easily know the friend are real or not with the time passing on. The time shows who are the real or not. However new friends musn't be easily trusted if u don't feel close. I trust on my old friends.

I do not test friendship but I notice if a friend is not real because he/she is just there in times of happiness, but when you are in trouble, she is not there to help you. I'm really not picky when it is about friends.
