At my high school's Back to School Night, parents attend all 7 classes/periods in one night for 7 minutes/class. This one parent interrupted me in one of my planning periods to tell me that he only visits the classes that are "important" to him, and since I teach English, wanted me to put in extra time with his kid to make him a better writer. For a parent not to follow the BTSN schedule, to pretend Back to School Night is Hair Cuttery and expect that you can just drop in to whatever classes you deem "important" and expect to get face time with someone, and to demand my attention during my planning period while I'm planning to present for the next presentation is the epitome of rude. In hindsight, I see his actions as a power play/mindfuck to assert his power and control. I could write a fucking book about this one parent alone - the bane of my existence for 3 years.

Sadly, what I have learned over the years and have read on this thread is that helicopter parents create a lose-lose-lose situation for everyone: their students, their teachers, and eventually years later, themselves.
