When my little sister was christened, my mum (who is an atheist) didn't go to the church - she stayed at home to make the food for the party afterwards. She kept me at home, because as I was only about 17 months old, she didn't think I'd stay quiet in church.
Apparently, this was the day when I learned that I could reach up and get things off the dining table - mum discovered my new talent, when she found me on the floor, with the remnants of a whole plateful of chicken vol-au-vents strewn around me!
Ds3 has a number of incidents that have gone down in family history. Like the time when, aged about 7, he decided that, as children at school had been calling him weedy, he needed to do exercise, in his bedroom at night, and started weightlifting with the 5l can of paint that we had stashed right under the back of his bed (where we thought he wouldn't even see it, let alone reach it). This went fine, until the night he dropped the can, the lid popped off and 2.5l of emulsion spilled all over his carpet!
His habit, if he'd had a problem like this, was to sidle up to dh and whisper, 'Dad, there's a problem' - in the hopes that I wouldn't find out what he'd done - and this is what he did when he'd spilled the paint (and trodden it down the landing, on the brand new carpet). Sadly for him, I was wise to this ruse, and followed them upstairs to see what he'd done!
Luckily the carpet was old and manky, and we managed to scrape and wash all the paint out of it.
Or there was the time when dh went upstairs and smelled burning from ds3's room - and when he went in, there was a delicate pall of smoke drifting across the ceiling.
He asked ds3 what was burning, and ds3, wearing his most innocent (and therefore most suspicious) expression, said nothing was burning. Dh was not fooled by this, and investigated, only to find a scrunched up piece of paper, smouldering behind ds3's desk, right next to the curtains!
Ds3 had been experimenting, to find out what happens if you scrunch up a piece of paper and tuck it alongside the lit bulb of your bedside light - and when it caught fire, and he heard dh coming upstairs, he threw it behind his desk, and hoped not to get caught!
