You know you're really tired when someone asks you what 8 x 4 is and you can't figure it out.
This also reminds me of a time when I hadn't gotten any sleep for 36 hours and as a result it took me 3 hours to do half of a "Very Easy" Sudoku, one that under normal circumstances I would have finished in 15 minutes tops.
Ah, the joys and perils of not getting enough quality sleep.
I was in the third grade. I don't remember what we were studying but I remember that our principal came into the room looking like he was about to cry and told us that there was something we had to see. I remember staring at the TV screen, watching the news report. I didn't quite understand what I was watching or what the importance of it was, or even why everyone was upset. It wasn't until my parents explained to me what happened that I understood.
Never forget the sacrifice that people made that day in order to try to save the lives of other. Never forget.
