I know there are more important things to get annoyed by but DD has just stopped using the pushchair. It really does irritate me when people ask me where my buggy is.
It is a pushchair, I'm pretty sure buggy was a brand name or model name of a particular pushchair. A similar situation to not all vacuum cleaners being hoovers.
So I don't have a buggy but my pushchair has been put in the loft for next time. AIBU to say "we have put the pushchair in the loft " in response to " what have you done with your buggy?" and similar questions.
