Girls and sex. Although they are interelated...
Some might also say that my liking and being most comfortable either on my own (or in a small group of friends) would be a vice/bad for me.
Mother has a go at me for 'not going out' but I think going out once a week with my mates is enough. Plus I go in town etc in the week, just I don't go out getting drunk a lot like she does... *sigh*
Would have gone out tonight but I'm knackered since I've been moving my uncle into his new house and its a heatwave or something today.
I think those are all my vices...
On a more cheerful note I can play Silent Night on the geetar! And I know about...5 chords (C, G, G7, A7, and D)
