One day in calculus, someone asked me how old I was. I wasn't really paying attention, and said 16. Then I thought "Wait a minute, I thought I was older than that." I changed my age to 17, and then wondered if that was even right. I got so flustered, and confused, I had to pull out my driver's license and see if I'd turned 18 or not. Of course, I had. By then, everyone was laughing rather hard, including myself.
OK, maybe these long stories are funnier to me than to anyone else. I'll see how many people read them, and reconsider the idea then.
