Do atheists believe in the existence of friendship?

[brewer]

Hi,

My first point from this question is that if an atheist believes in the possible existence of friendship between two humans, how does he define the best friendship? (Please be aware, it is a tricky question )

Thank you.

The ones that would take a bullet for me.

Unfortunately everytime one tries to prove it the list often grows smaller. (some only get flesh wounds)
