Recently, I had the pleasure of meeting J - who was at school with Mr Twinky, my evil sidekick cat. They didn't know each other in those days, but J had recognised Mr Twinky when he had been through in Glasgow, and they'd had a coffee and a chat and they'd ended up keeping in touch.
So we went through to Glasgow, we met J, we hung out, had some beer, had some food, talked about a lot of stuff, and ended up watching a movie until the small hours of the morning.
In many ways, J reminded me of how I might have turned out if I was single - and he also kind of reminded me of a 23-year-old - still living the lifestyle of someone fresh from college. In some ways, though, he seemed very set in his ways.
I know I can be set in my ways. It's a function of being middle-aged, I'm sure. And it's not necessarily a bad thing.
