I was supposed to go to sleep early but then I realized I was too hyper after getting the result of my grammar exam (too much coffee as well
), that is why I stayed up to study. I can't claim now that I have learned a lot though.
I oversleep all the time when I have a day off and don't set the alarm clock to go to the gym.
Oh yeah, how lot of times it happened to me, on the school. I was excited about practice, or something happened and I was too hyper as well.
And when simply I didn't want to go to bed and I stayed awake until 1-2 am, you can imagine how I could wake up at 5.
Or when I watched Kubot until 4 am.
