An odd thing happened to me as I left the tube to go to my meeting. There was a big issue seller outside the station. I am certain that I recognised him from the past few years at Crisis, so I said hi, bought his magazine and told him I didn't realise he sold the big issue and asked how long he'd been doing it. He seemed not to know me. So, either I'd been mistaken or he had forgotten me. Context is important when it comes to recognising people. So perhaps it was who I thought it was, but I need a Crisis shelter and a badge for him to know me. Either that, or I just confused someone. Maybe he'll go through the day wondering who the hell I was and whether he should know me. Maybe he'll think that I was just a stranger being friendly, in which case, maybe he'll wonder why I said what I said. 'I didn't know you sold the big issue' - surely the package of them in my hand was a give away!?
I must remember to bring this up with the chap if I see him this year in the context of a Crisis shelter, though it would have to be brought up sensitively. You can't just ask a homeless guy 'hey didn't you sell me the big issue once?' it looks like stereotyping and he may take offence.
