A favourite ploy was to ask trick questions to encourage the class to think around problems. Some of them could be quite strange though and often left the class looking somewhat bemused. One classic was:
"I was out in Southend at the weekend. It was a lovely day so I took a stroll along the pier. Whilst there, I witnessed a young mum push her pram off the end of the pier, with her baby in it. What did I do?"
There were the inevitable looks of shock and disbelief and obvious suggestions such as ringing the police and even jumping into the Thames to effect a rescue. However:
"I did nothing. Why?"
This challenge was accompanied by the trademark hard stare, which was returned with a class of blank looks.
"Well, I haven't told you which end of the pier it was, have I?"
