A.A. Milne -- yes, he of Winnie the Pooh fame -- wrote in a story in
Punch years ago, now in a fun collection published in 1929 called
Those Were the Days, of a house guest who paused during a breakfast conversation to eat an orange:
Five minutes elapsed, or transpired (whichever it is), before I was ready to talk again. Generally, after an orange, I want to have a bath and go straight off to bed, but this particular one had not been so all-overish as usual.
That's exactly how I feel after an orange, or a grapefruit! Perhaps they're better as bedtime snacks?!
