I know it is stupid and something that shouldn't bother me. I am just afraid that one of these days, I'm going to forget she hasn't cashed the check yet and make a purchase that will result in her check bouncing.
I tend to be pretty good about remembering that my balance is $X-$750 or whatever it is I write her check for. Buying christmas presents the other night though, I almost made that mistake and it just got me thinking about it.
