Sneaking in Snacks at Night

I know I shouldn't admit this as a parent, but here goes. My teenagers love their junk food and I secretly stock the fridge with all sorts of treats, chips, candy bars, soda, at night when they're asleep. It's my little rebellion against all the healthy eating rules we've set for them during the day. They think it’s just their granola bars and yogurt in there but I'm giving them a real treat. Sometimes I feel bad about sneaking around like this, but mostly I just can't resist seeing the joy on their faces when they find these surprises. If they ever caught me, I probably wouldn’t stop doing it though, too fun to see them happy.
