Not too sure what it is about mothers at the moment. So far, one friend has supplied me with a couple of Gems from her mum - and assures me there'll be plenty where they came from. Now, Sharron has come to the fore and come up with something from her own mother. I have to admit, though, it's more of a'Fail' than a Gem.
Apparently, the family were sat around, watching Agatha Christie's Poirot on TV. You know - that famous detective from Belgium. The one best played by David Suchet.

Some way into the programme, Sharron's mother evidently has a flash of insight.

Well, yes. Yes, i... Actually, no. No, it's not. It's not 'just like' a whodunnit, it IS a bloody whodunnit.
Fortunately, what with everyone else giving her carefully blank looks (laced with a modicum of humour), Sharron's mother quickly realised what she had just said and led the laughter. Which, I am told, lasted a fair few minutes.
