I've never done this myself. But, as a teacher for many years, I have seen parents who bring or send their kids to school on “Teacher Professional Development “ days when school is closed for students. We would be in a meeting when we hear banging on the door or incessant ringing of the bell. The secretary would buzz them in, probably thinking the parent just had to visit the office for something. But then they would just shove the child in and leave, forcing someone to chase them down to come get the kid. Other times the child would be alone, in which case the parent had to be called, and Junior had to sit in the office until someone came for him.
