In my only year as a schoolteacher aged 22 I was dressed up in full Santa disguise,red dressing gown,white hair,long white beard, etc. I took off my glasses and climbed on to a low slung dinner trolley with a big sack of presents and was towed in to the main hall where the younger classes were sitting in eager anticipation. In true Santa fashion I boomed out "Hello children!"
and my class of seven year olds responded with their usual chant;
"Good mor-ning Mister An-drews".
