I don't even know where to start. As a child I was socially clueless and blunt at times, scornful of weakness, had a bad temper, hated having to be with people I didn't know well, gave into peer pressure despite having qualms, and I irrationally disliked a few individuals. When I got a bit older I was an asshole towards quite a few of my friends, I was an opinionated pseud-intellectual *****, and I was really socially awkward and shy which made me come across as stuck up sometimes. I also put unnecessary stress on my teachers because I was always late and disorganised.
Nowadays I'm more the lazy apathetic brand of asshole who hypocritically points out flaws in other people's ethics and acts aloof without bothering to explain my disdain for something out of laziness, fear of judgement or looking like even more of an asshole, and then just lets a bitter remark every now and then. I avoid everyone at church and rush to sit in the car even if it's like 40 degrees. I was reluctant to make plans with my friend to celebrate graduation. Sometimes I'm terrible with giving presents on time, or giving presents at all. I think about being straight-forward and saying "can we not do the presents thing? It creates unnecessary stress, we don't need any more stuff, and we don't need to buy each other stuff to prove we care about each other (unless we actually need something)." Then I feel like I'd sound like I was being ungrateful for stuff they've given me in the past, then I just get pissed off and feel personally victimised by the TV and all the nice people following conventional consumer obligations and "lovey-dovey" expectations and I still feel like an asshole and there are probably more things >_<
edit: Then there was that time I watched a guy get beat up by some hobo looking guy while screaming and then stumble away and I was so shocked I didn't do anything except shakily go to call the police. I'm still angry at myself for not at least yelling or going to see if the guy needed help after the man who assaulted him ran away. We were just like "never mind, he'll be alright, he's limping away leaning on his bike..."
And there was that time a stray dog kept running on to the road and we didn't even think to stop it, and this lady grabbed it and told us off, and we said "it's not our responsibility".
