Sorry, I slept through the movie....again

Last night I was watching Harry Potter and The Half-Blood Prince and I never got to see the ending of it. My mom said that it was a good ending, but I totally missed it because I fell asleep on the couch trying to watch it. The worst thing is that while I was trying to watch it I kept nodding off into sleep. I was so looking forward to watching it but I am so mad that I fell asleep trying. Then, I end up waking up at 12:30 in the morning asking my mom when did they finished watching the movie. She said that it had finished while I was sleeping on the couch. She said after that, she asked me if I wanted to go to bed and I apparently said that "I want to stay up." but then I fell back asleep. I woke up like I would say 20 minutes later and asked my mom what is she waiting for. I then said according to her that I wanted to go to sleep and then that's when I asked her what is she waiting for. She then proceeded to ask me the same question, mind you that I was still half asleep asking her these questions. I think I told her "I'm waiting for you." and then I went to bed 'cause I was dead tired. Oh well, I guess I have to see that movie another time.
