I've been reading ehell for years but never ran across a movie theater SS--until yesterday.
I took DD to Frozen for the second time. The theater was surprisingly busy, considering how long the film has been out. Anyhow, it was pretty packed. A couple with three kids sat behind us. The mom bickered with the two older kids about passing popcorn, getting situated, etc., which was a little annoying as they'd arrived right as the previews started to roll. Then she and the husband discussed some of the movie previews, loud enough for me to hear them. But ok, the movie hadn't started yet.
Their youngest was older than a baby, but not quite a toddler--probably 18 months or so. He sat on Dad's knee for the first half of the movie, and was kind of noisy. Again, ok, it's a kid's movie, and happy baby noises are fine. But both his parents started asking him questions that they expected him to respond to, and cooed at him when he did..."What noise do horsies make?" "Oooh, isn't her dress pretty?" "Can you say snow? Yes, snow! Aww, so cute!"
So about 2/3 of the way through the movie, I heard the mom say, "Someone has poopy pants!" My first thought was, "Great! I'll get a few minutes of quiet." Then I heard velcro ripping, and look over to see the baby standing with his face 5 inches from my DD's head. This made him extra excited, and he started squealing and shouting. Yup. Mom is changing his diaper in the middle of the packed movie theater.
When the movie ended, the mom burst in to song during the credits. I couldn't help but think of the poster with the tap-dancing MIL.
