Random examples:
Lust: I'm 22, married for a couple of years and started fooling around on my husband a few months ago. My hubby and I seem to have almost no sexual chemistry between us, where my male friend and I can't keep our hands off each other. I've even let him fuck me in the ass several times, when I won't even let hubby near it. I also swallow his cum. I feel bad about this but I can't stop.
Pride: In order to get myself out of bed every morning, I look at a picture of me and admire my beauty, then I shower because I feel disgusting.
Greed: I (male) fucked my friend (male) because he gave me $300 on a loan. I knew I wouldn't have to pay it back and I haven't. He'll never mention it. I wish I could do it all the time. I'd be drunk a lot though I think.
Gluttony: Nobody drinks like I drink, with the possible exception of the consul in under the volcano, for god's sake. I've been drunk since I was fourteen. You may think you have a substance abuse problem, but this is what I drank yesterday (a tuesday, no less... ); six cans of heineken, one litre of red wine, twenty ounces of vodka... then I went to the bar where I proceeded to drink four shots of whiskey and four pints. I have been in the drunk tank a bunch of times, lost every job I've ever had, never finished university and lost my drivers licence. Its four in the afternoon, and you know what I'm going to do with my day? Go rent moby dick on dvd, pretend I'm captain ahab and drink a bottle of rum like a mentaly retarded pirate. I don't feel the slightest bit of remorse for being so utterly useless, because I'm really good looking and alarmingly smart. I am supposed to be working on a novel, but instead I spend hours in the gym every day to maintain my looks and conceal the fact that I am a shit filled piniata on the verge of full-blown liver damage.
etc.
