It looked as though it 'might be important'. It might just happen that in three years' time we'll realise that a tube thing with a serrated bottom is the missing part from the thingummyjig that we haven't been able to work out how to use. So we kept it.
It's been sitting on the kitchen counter for some time, just next to where we sit to eat so Husband and I have occasionally engaged in a guessing game. 'Could it be a ...?'
'Nah, but what about a ...?'
'I don't think so. But perhaps it's a ...?'
Then Husband came up with a good idea.
'Nah,' I said. 'Surely not? How would that work anyway?'
'The only thing to do is give it a try.'
So this evening I did. And it worked! Though why Uncle would have had one of these in his flat is anyone's guess.
