Evolving Views of Friendship

I had an online conversation when I was a teenager about what a friend was (and I feel like I've written about it before but I couldn't find it so perhaps not). I argued that a friend was someone with whom you could be completely yourself, share anything. The person I was talking to disagreed. He said that was a far too narrow view of friendship basically saying that that was impossible. 

I think he was right. Perhaps instead I will define a friend (for now) as someone who appreciates you when you are being you. Being your most you.
