Toothbrush down the toilet

[KindergartenKop]

While brushing my 4 year old's teeth today he told me (laughing) that when his grandad was looking after him on Tuesday, my electric toothbrush got knocked off the sink and into the toilet! Apparently grandad did wash it. Aibu to be annoyed?

Nope nope nope. The whole hung would be in the bin and I'd be vomiting. Nope. Nope. Nope.

I can change it, but I've been brushing my teeth with it since Tuesday!

YANBU - really unacceptable he didn't tell you, no way would I use a toothbrush that had fallen down the loo.
