Nearly put my foot in it a few minutes ago.
I saw a work colleague and, vaguely remembering something about her dad being poorly, was on the verge of saying (in a friendly, chatty way) “How’s your dad?”
Fortunately I just remembered at the very last second what was wrong with her dad – he had just died!
It was good that this came to me, otherwise it would have been, like – “How’s your dad (pause) still dead?”
Yeah, I know – sorry about that – it sounded a lot funnier in my head.
