I set a curfew for my girlfriend because she has been spending too much time with her friends, which I don't like at all

It was past her curfew and she still didn't come home and that pissed me off even more,she didn't even text me to say that she's coming home late but she didn't and that makes me mad

I then turned off the lights but before that I put a chair in the in front of the door and then I turned off the lamp,after a few minutes of waiting she quietly opened the door and tried to sneak inside but then I turned the lamp back on

"Who were you with the entire night!?"
