to ask where the vacuum cleaner is?

[DysonSchmyson]

Was asked to empty it out. As I got up, I asked whether it was under the stairs. Cue a bollocking that it's been there for seven years so I should know where it is.

(Sometimes it lives in the spare room if we're mid-clean).

AIBU to ask?

Ouch!!!!

Sorry...but nope...YANBU to ask. You could have checked though instead of asking?

Cupboard under the stairs with a load of junk we shoved there when we moved in vitally important tools.
