I'm thinking of my mom scolding me for an hour about acting like an adult.
Why did she scold you?
She told me to be home at 8:00pm, but I didn't get in until 8:25pm.
It is understandable why she would be upset and you need to act like an adult. If your mom tells you to be home at one time then you shouldn't come in way later.
It was only 25 minutes.
That's a long time to wait when you don't know where your child is. If you wanted to be treated like an adult then you should act like one, starting with coming home at the time that your mothers asks.
