There are obviously different types of children. When I was in elementary school, I made a really stupid comment about a game my friends and I were playing, and even though my friends didn't say anything about it, my stupid comment haunted me for years, even though I was the only person who remembered it.
Strangely, I'm old enough now that I don't remember the comment, and I don't even remember the game.
Anyways, my memories lingered, even in childhood. But I think I had more fun back then. The highs were definitely higher, but the lows were lower, too.
