Why he mad?

My bf works 3rd shift so he sleeps ALL day. I, however, like going out occasionally to spend my day out of the house.

I decided to go out 30 minutes from the house and he calls me and gets all worked up as to why I left him home 🙄

Why is he mad? He's sleeping. He needs sleep. I want to get out of the house.

Edit* yes I leave notes
