I remember the time when my son was about 4 years old and he disappeared from the living room and had gone suspiciously quiet. I'd have investigated sooner except that we had visitors - the minister and his wife.
I soon discovered what my son had been up to. He came back into the living room clutching a box of condoms and had one hanging from his mouth - bad enough, but his asking the minister to "blow up the balloon" for him was just too much!
