Some might be embarrassed to admit to something like this, not me though.
I had never known of the phrase "an elephant in the room" until a few months ago. I suppose I had heard of the phrase, only in the context of there actually being a pachyderm lurching in the environ.
A year ago, had I been sitting there having a quiet beer with you, or you for that matter, and you'd mentioned an elephant in the room, I'd have jumped up and been searching like Clouseau looking for Kato. Nowadays I know that it's a lovely little metaphor and I chuck it into a conversation at every opportunity.
I suppose the only potential time for confusion would be if I was in a bungalow in Yala and someone mentioned the matter. Things could get very puzzling.
Must dash, there's something hiding behind the curtains.
