Hee hee, the ambulance peoples we saw at the weekend nearly fell over backwards when we said we didn't want to go to hospital. My basic-level 'things' are keys, phone and money (usually in my purse). If I'm leaving the house for more than, say, half an hour, then I'll also want my painkillers, a pocket pack of tissues, and a tiny notebook and pen... and if I'm expecting any periods of sitting-around-waiting then there's a small knitting bag containing half a sock. Oh, and in winter I have this gel thing where you click a metal thing inside it and it crystallises and is warm. Beyond that, my bag-size directly correlates to my stress levels. If I feel relaxed, I'll cheerfully go out with everything I feel I might need slipped in my jeans pockets. If I'm really tense, I'll be carrying everything from spare batteries to sun cream to two books (in case I finish one).
