Last month I saw a funny scene outside the Kreta Ayer People's Theatre. An opera troupe from China was performing during that period. It was early evening and two artistes were outside.
The man crept quietly up to the woman's back. Then, I think, he pretended to paste something on her back. She turned around and he darted away. Quite amusing ... suddenly they looked like primary school kids up to their childish antics.
So, don't think only children play the fool, adults too.
