The high school kids that ride my bus home from downtown make me feel like an old curmudgeon. I seem to find it really easy when I’m around them to forget that I actually like teenagers. They do most of the same things that all other annoying passengers do (talk loudly, jostle your seat, use their cell phones, recline the seat in front of me), but they do it in groups of 5, instead of just as individual annoying adults. Last night there were at least a dozen on the bus instead of the usual 5, and they were entirely obnoxious (and, as is always the case with annoying people, completely oblivious to the fact that there were other people in the world). It made me grumpy.
