Hi,

The speaker didn't forget the keys because you can't really forget keys, can you? He left them in the door. He forgot to take the keys out of the door.

Hi

Sorry for the off-topic...
But what was/is always intriguing to me: which form – plural and 'pattern' (keys) or single (a key, my key) – should I use if there is only one key on my key ring?

(By the way, to me, personally, when a person says 'I’ve lost my key' – he/she more likely means that he/she has forgotten/lost a (software) product key. )

HI Tamara,

Keys aren't glasses (spectacles) so if you've only got one key, then one key it is as in: If we're not back before you go, leave the key under the mat.
