I care about my wife and kids and immediate family. I have 5 close friends and we grew up together and joined the army together so, quite literally, relied on each other to keep each other alive.
I have no interest in other people.
I have no "dickish" reason not to care about other people it's just purely down to I don't know them, I have little interest in knowing them and if anything happened to them it wouldn't affect me in the slightest.
I suppose thats a little harsh, if I saw someone getting a severe beating off a group of lads i'd stop to help them, mainly because I like to fight and my wife doesn't like it so that way i'd have an excuse, and the fact I can't stand people that need 8 friends to fight 1 person. If folk are too scared to fight 1 on 1 then don't fight at all .... pussies.
Or if I saw an elderly person having a problems i'd give them a hand.
I'm not an utter bastard I just have too much time worrying about my own family and friends to give a shit about other peoples.
