When I was a small child I was very, very superstitious. Very. I was brought up in a household where my grandmother would say a novena at the mention of bad news and my mother would say things like don't put shoes on the table, it's bad luck. Black cats, walking under ladders and broken mirrors were taboo. Of course, when I broke a thermometer on the bathroom floor and played with the balls of mercury for a half an hour, no one batted an eye, but shattered glass?
The horror! You'd better get the rosary or start knocking on wood.
