Spot on Mr M! They are parents of an ex or former pupil of yours unless, of course, they've been through some legal process to rid themselves of him.
I stand corrected. 👍 I should have simply said, “they are parents of a boy I taught.” I blame my ineptitude on the weather. 😉
Could be Mercury Rising - in astrology, not the film. Someone said that the other day to explain away their clumsiness and it sort of stuck in my mind.
It was a lovely day here too but the temperature took a nosedive this evening. We put the heating on for a bit to take the chill off. Heating is off now but the house is still comfortable.
