My child has been a school-ager for all of 7 weeks now and I have decided I hate enrichment activities. I hate gymnastics because it is too far away and there is nowhere to wait safely and sanely with a 2-year-old in tow. I usually flee to Wal-Hell (to borrow Jamie's term) and that should give you an idea of how awful it is to stay at the gym.
I hate swimming because of the changing into suits/changing back to clothes, the grungy showers, the (again) dealing with the toddler in the locker room.
I hate soccer because I had to sign up two weeks ago (and pay $85) for a season that starts next May. And I had to pay an extra $25 so I wouldn't have to be an assistant coach or some other ill-defined volunteer job that I have no interest in or time for.
I hate dance because of the inappropriate songs and costumes (Chicago's "All That Jazz" for 4-year-olds, anyone?).
I hate music because my son opts to stand in the corner, crawl under the table, or throw things and I'm left scraping sandpaper all by myself.
I do like Sunday school. It amounts to free babysitting and there are doughnuts after.
Tell me it gets better when the kids get older, and I just sit in the car with a book while they're off somersaulting or playing the French horn or whatever.
