the corner office

All within 10 minutes of Father and Son entering the local Tesco:

LOOK DADDY, THAT BOY DOESN'T HAVE ANY FINGERS

(poor disabled kid who works as a trolley-collector trying to tell me we've dropped one of our carry-bags)

LOOK DADDY, THAT MAN'S ONLY GOT ONE LEG

(poor geezer on a mobility scooter)

DADDY, THAT MAN IS FATTER'N YOU.

(excessively hefty dude serving us at the fish counter)
(Thanks, son).

After each of these episodes Father patiently explains to Son that people are all different and there's nothing wrong with that but that it's not polite to say things about people because they might hear and be embarrassed, and if Son wants to tell Father he should wait until we are away from the person and he can tell me quietly.

So soon, we have

DADDY, THAT LITTLE BOY ... (Leo, what have I told you about talking about other people?) silence

Down the next aisle ... "what did you want to tell me about that boy?" "He had a Spiderman toy."
