Following on the childhood theme - what completely weird things did you do as a child, that make you cringe thinking about it now?
For some reason (around age 10) I didn’t like the rolls my mum made me for lunch. Instead of chucking them in a bin like a normal person I’d lob them out my bedroom window to the outside of our garden on a bit of communal grass. They’d get mostly hidden by all the leaves and cut grass. Eventually my dad noticed lots of rubbish and investigated it, finding several weeks worth of mouldy packed lunches.
