One way you know you're getting old

We went to Grandparent's Day at the local school; this was our last time at this, since Grandparent's Day stops with the sixth grade. We found Natalie's room, stepped in, and were seated. I kept wondering, Where's the teacher? Is she sick, and they've appointed a high school kid to help out today? Couldn't they get a subsitute teacher?

Finally, noticing how this "high school boy" was taking charge, I asked Natalie, "That isn't your teacher, is it?"

Yep.

My sixth-grade teacher certainly didn't look like that!

The older I get, the younger the teachers look.
