I carry a plastic tesco's bag for life around with me, although I really ought to get a cloth one, seeing as how the plastic one is looking a bit manky. Occasionally I have to top up my supply of proper carrier bags though, because they're handy for stuff.

Positive thinking. Well, I'm not actually very good at it. I am quite attached to moaning about everything. I just thought I'd give it a go because I suspected the constant moaning was starting to make me feel worse...
