When I was little, I would wake up in the middle of the night and have a great idea... I would run to my parents' room, wake them up, and, a little to loudly say "Guess what?! I have an idea!". They would reply "huh?......what is it?..." Then I would say "awwwww...... I forgot" and they would say "uuhhh.... just go back to bed...". And guess what? That happened A LOT. Of course I was too young to actually remember this, but my mom told me about it.
