There can be few things so embarrassing or troubling in a parent's life as being called into the Principal's office. If you thought it was bad as a kid, it's nothing like being the so-called adult in the relationship and still not getting it right.
The other day when Sean went to pick up Aedan at preschool, he was pulled into the office by Aedan's teacher (okay, so it wasn't exactly the principal, but it feels pretty much the same). She informed Sean that Aedan seemed to be having some trouble listening and behaving in school. She had tried several different things, but they hadn't worked so far. She had a few more ideas, but she wondered what we were doing at home and if he behaved differently there.
