Mine was years ago, just a kid, sitting on my bed, just finished reading a comic book after school. Mom comes in and says something like it's getting late, better get ready for bed? Really, It's still early, we just finished dinner. She says, no, you've been in here for hours. I persist saying i've only been in the bedroom for maybe 10 minutes, long enough to finish reading the last couple of pages of my new comic book. She has me get up and come out to the kitchen.... it's 9pm! so instead of only 10 minutes, it was over 3 hours. I couldn't have fallen asleep sitting up, plus I wasn't tired. I do admit i was staring off out into space thinking about something for a few seconds, but over three hours? How the hell could that have happened?
