step on a crack, break your mother's back

I am issuing a formal apology to my mother.

When I was really really little and really really mad at my mother, I intentionally stepped on every crack in the sidewalk, not knowing, of course, the reality of these such things.

Sometimes, nowadays, when I'm walking down the sidewalk, I go out of my way to step over every crack, in hopes that maybe I can kind of take it back.
