sleeping in on a school day

I got mad at my mom today because she let me sleep in on a school day. that sounds cool but she didn't tell me about it. so I woke up thinking that it is early in the morning and my mom would come in and get me. but really it was 1:00 o'clock pm. so I have less time to do every thing I need to get done and I don't want to still be doing school at 6:00 o'clock. I don't think I'm mad that she let me stay up it's just that it fells like I don't have a opinion in my own life.
