So from time to time, my dad will be on his computer, going insane over some funny YouTube videos. So far, he's the only person I know of, that will laugh carelessly at his computer to some of the most ridiculous videos you could ever see.
My dad is truly a child at heart; something I hope for when I grow older. He's always laughing randomly at things, or he'll burst into a repeat mode of crazy tunes and jokes for hours on end, until eventually...he's driving you crazy.
Either way, it's great to see his happiness from time to time; it's nice to know that maybe getting old isn't such a bad thing...that there is something good to it after all
