My 4th and 6th grade daughters went to class with me on Friday (after a week of snow days you run out of other things for them to do). Afterwards, one of them, a bit embarrassed (for me it turns out), asked "dad, did you know that all of your students weren't paying attention?"
Yes sweetie, I knew that.
Then the other said, "yeah, one had his head phones on and was watching hockey! and one was texting the whole time!"
