Things that ruin your day>?

When I am busy doing something like cleaning my room and my mom or dad barge in and tell me to clean my room, makes me not want to do it anymore here's a couple examples.

They hear the vacuum running: "Can you vacuum?"
They hear the faucet on the kitchen sink running: "Can you wash the dishes?"

And when you realize your phone didn't charge properly overnight and is now at 5% battery.
