i think it depends on the circumstances in which I'd meet myself. if I was in need of some help and clone me lent a hand, or if we met under friendly circumstances, we'd probably become good friends, and then whenever he did the douchey things I tend to do, I'd excuse him and be like "lol well I bet i would do that too so I shouldn't judge." we'd probably have great fun being assholes together. if we were strangers and I saw my clone acting like the asshole that I usually am, I'd probably hate that guy and call him out on being a dick.
in a similar vein, look at your friends currently. how much of their bad behavior do you excuse because they are your friends. if you were strangers and your friends acted the way they do, do you think you'd want to befriend them? an interesting question indeed. so then are they friends simply because of circumstances, or are they actually people with whom you want to be friends?
the above was an interesting question I thought about today. it was prompted by my friend saying to me today, after I made a pretty douchey comment at some circumstance idr what, "you're lucky I like you man or else I'd judge you so hard"
