New-style birthday

It's my son's birthday today! Happy birthday, guy! You're a teenager now! And your mom won't be sleeping well for the next ten years or so. But today, we celebrate. Then we celebrate again on Sunday, when he has his birthday party with friends -- a dozen kids from his special education class descending on a bowling alley. Fun times, for them. For me, it's making sure that boys do not go into the men's room together, because they'll certainly do what my son is constantly crowing about as "the new-style flush," which involves hitting the handle with your foot. This is, of course, ever so much more fun when you have an audience and can show off your extreme prowess at kicking plumbing. Are teenagers supposed to find such things so overwhelmingly hilarious? He's thirteen in years, but still a kid at heart.
