The ambulance thing - we had to hold our collar until we saw a four legged animal, and that way we'd never ride in one.
We had to eat our crusts in order to have strong white hair and big curly teeth ... my mum knew all about the Rev. Spooner.
Avoid treading on the gaps between the paving stones and get downstairs before the upstairs loo stopped flushing to avoid all kinds of problems with monsters and snakes and stuff. I remember getting very confused in Eastbourne (where my grandparents were living) because their pavements looked like blocks of Dairy Milk with the raised chunky bits and that was where I saw my first ever black person. Apparently he was very amused when I told my mum he was chocolate too - I'm glad he saw the compliment I was intending it to be!
