I remember those days. xD I used to get into trouble in middle school and high school not for doing things like coming in after curfew, but for staying up reading or on the computer past 'bedtime'. >_>; I think I spent most of my middle/high school years living on 6 hours of sleep a night. :x
When I was still in high school I had the same issue. I wouldn't sleep until 3. It started out with my mother taking away my keyboard... which then I would pull up the onscreen... and then escalated to the whole screen being removed as well. ;_; Oh what a sad time in my life that was.
