I think I'm fairly good with money, but I've developed some strange tics - in shops I don't like to go to the counter unless I've got at least two things to buy. If I'm walking around with just one thing in my hand I'll put it back and wait a few weeks because that doesn't seem like a proper purchase.
Philately is normally a boys' hobby but for some reason it was in vogue at my junior school. Between the ages of eight and ten I collected avidly. I'd pore over my Stanley Gibbons book, obsessively checking my collection's value. I always hoped I'd stumble across a really valuable one, a Penny Black or an Inverted Jenny, but it wasn't to be.
