Because in the Catholic religion you do the sign of the cross before and after basically everything you do, I thought it was a on/off switch for talking to God. But I couldn't remember how many times I'd done it, so I was never sure if the switch was currently on or off. I was terrified that I was talking to God during the wrong times, and he wasn't hearing me when I was at church. So every week at church I crossed myself twice when I sat down so that at least 50% of the time I was right.
