Perfectly normal Mum! Nothing wrong with that at all!
I've taken to cutting up every cardboard box (cereal, tea etc.), and using the pieces for lists all over the house, including the loo and the shed!
Mrs Growster started to despair at one stage, but we both live by these lists now - there's even one Sellotaped to the freezer, to remind me to keep the door shut, as it sometimes keeps open a bit! (It was even open just a few minutes ago)...
When I do the shopping, it's written on one of these lists with a bulldog clip so I can attach it to the trolley, and I now have at least seven similar lists in my pocket, all stuck together...
So a simple teabag episode is a mere drop in the Typhoo...;0)
