i had a blast from the past the other day. i met an old student of mine (she was 10-11 when i taught her), who had severe behavioural problems. she recognised me, and was really enthusiastic about talking to me, which my ex-students always seem to be.
she'd been kicked out of home and was living rough, or sleeping on the floor of various friends. (she's 18 now). anyway, i chatted to her for a bit, and bought her breakfast as she had no money.
it unsettled me a little, though - i wondered if i was being taken for a ride. sometimes, i can be too trusting. typical aspie, i s'pose.
