The $20 I took from Mom

Okay, so this is stupid. I'm 35 years old and I still feel guilty about this. When I was maybe 8 or 9, my mom had a twenty dollar bill on her dresser. She was saving up for something, I don't even remember what now. I wanted a toy, probably some dumb action figure. I knew she wouldn't buy it for me. So one day, I took the twenty. She asked me if I'd seen it, and I lied right to her face. I said no. I bought the toy. I played with it for a week, maybe less, and then I forgot about it. But I never forgot taking the money. I still think about it sometimes, and I feel like such a terrible person. I wish I could go back and not do it. Or at least tell her. But she's gone now, so I can't. I hope she somehow knows I'm sorry. It's a stupid thing to feel guilty about after all this time, but I do.
