A good friend is 100% honest about themselves, and how they see you. AND, their perception of you is naturally positive because they genuinely value your real self.
A best friend is almost like real family, a best friend gives the opinion you usually care most about. A best friend is the one who tells you the things you absolutely need to hear regardless of whether you want to hear it or not. A best friend is the person you usually can be around always and never get sick of. A best friend is someone you don't envy, and is the person you are grateful to have as a friend.
