Marking

I usually have something funny to write under this heading, but not this time! I don't know whether I've lost my sense of humour about it all, or whether there actually hasn't been anything particularly funny.

One guy wanted to train a person to be anxious when they heard an ambulance siren by orchestrating a meeting between the subject and an ex-con on the street. The ex-con would then proceed to threaten the subject, while an ambulance drove past. Not the most intuitive method, but I suppose it would work.
