To consider someone a friend, what do u have to do?

I personally think a friend is someone who you can turn to when you need emotional support, someone you can turn to when you want to share your most happiest moments, and someone who even if you have nothing to say you still just want to connect somehow with. I believe a friend is a person who makes you feel so comfortable with who you are, someone that will not make you feel embarred or bad when you express yourself.
