Reading this, I realize that my life hasn't had many ups or downs at all. I'm pretty indifferent almost all the time, but I'd say that just spending time with my best friend in grade school were my favorite moments. Like when we were hungry, and decided to make popcorn on the stove, and ended up putting all sorts of fucked up ingredients in it, like tobasco sauce and ground peanuts, and it obviously turned out to be a giant mess. Or when we were playing catch, and the ball rolled into the street and down the sewer, so we tried getting it out, even to the extent of getting a crowbar and trying to pry it off. I don't think there has even been a defining moment in my life where I've looked back and said "this is the best moment of my life", but I've just enjoyed all the simple, dumb stuff like that.
Man, this feels like one of those corny tv shows where an adult voice is narrating a show from the 50s saying "when I was growing up, times were so simple in my neighborhood..." and shit like that.
