http://www.mumsnet.com/Talk/amiibeingunreasonable/3959655-To-ask-for-your-weird-family-behaviours-that-you-didnt-realise-werent-normal-until-you-were-older, what weird family behaviours will our dc be posting about when they are adults?
I’m sure my dc think that dunking biscuits is normal. You’re thinking about cups of tea, aren’t you? Dunking biscuits was the way we used to put our dc in the bath: hold them upside-down and slowly dunk them in head-first. Only until their hair got wet. Then we’d turn them the right way up. They were very sad when they physically got too big for us to do it any more.
Or the appalling consequences we threatened for minor annoyances, such as “Do that again and I’ll stuff you backwards up the chimney.” (We haven’t got a chimney.)
