Is there anything in the talk guidelines about them? I mean the 'I was sitting in Starbucks in Slough when a woman came in, aged about 40 with long blonde hair wearing a black jacket and she was screaming at her 3 year old DD because her DD kept messing about with her glasses.'
It's obvious, if you're that person, who they are. I've seen a few and I really don't like it. I'd be so embarrassed if it was me.
