This is rather delicate.
DD's bedroom window has a clear view down into next-door's kitchen.
At bedtime DD drew my attention to several mice who were bolting out of the kitchen skirting, feasting on crumbs and generally having a high old time while neighbour (who is very nice, tho' not a bosom pal) was safely away upstairs giving her many children baths and putting them to bed.
What's the etiquette here? Would you want to know? (I would, I think.)
