Best friends

Best friends are those people who act natural around you, don't "play roles" and accept you how you are. They welcome you in their home and let you do everything, as if you were home. Also they will honestly tell you how they feel about you and let you know when you did something wrong. In return, you must be the same, and then this can be called a true friendship. People come and go, but true friends don't. They stay.
