I've been stealing coffee from my mom for years and she still gets the 12 shot Nespresso machine filled every morning

I've never been in trouble for it. My mom has a tendency to punish after the fact and not when the deed is done. She'd find out after a few days and then just stop filling up the machine all together. I never told her that I was the one taking it, because I always filled it up the next time so it looked like I wasn't stealing at all. My mom also has a tendency to give me a lot of warnings before she actually enforces any punishment, which is why I've never actually been caught. It's a funny game I play with her and I don't know why but I love it.
