High School Musical

This morning on the way to preschool Ben and I had the following conversation:

[BEN]: Why am I growing so slowly?
[ME]: You're growing fast. I'm not growing at all any more.
[BEN]: When did you stop growing?
[ME]: In high school I guess.
[BEN]: What's high school? High School Musical?
[ME]: What do you know about High School Musical?
[BEN]: It's a high school where there's music.
[ME]: It's a movie. High school is where big kids go to school.
[BEN]: I don't want to go to High School Musical when I'm a big kid.

Some of his friends at school must have older sisters. The other day he asked me who Hannah Montana was.
