A childhood belief about bathrooms

When I was very young, my father used to sing me a little song while he bathed me. It went "my baby has gone down the plughole, my baby has gone down the drain. My baby has gone down the plughole, I'll never see baby again!" he used to sing it in a very sad voice. I believed that if I didn't cling on to the side of the bath I would go down the plughole and have to live with all the other babies who'd suffered the same fate. I was too small to hold on to the bath and I used to scream and scream at the mention of having a bath not because I didn't want to live in the drain's with the other babies but because I didn't want to make my father sad!
