Cherub asked Tevye if she could do some random thing ...
Tevye: We don't normally do that.
Cherub (hopefully): Perhaps we could do it occasionally?
Whenever we go to the local country park, Cherub insists we all have to play hopscotch - her rules - on the stone sundial. Last time we went she watched Tevye with a critical eye. Her verdict ...
"Daddy, you are WUBBISH at hopscotch!"
(Unfortunately for him, being rubbish didn't disqualify him from having to play.)
Cherub has decided (for today, at least) on her future career. She wants to be a "photoglipher".
