Teachers already here enough weird things from students in the classroom, so the last thing they need is the parents one-upping the student's with these dumbfounded statements! Whether it be complete ignorance, overprotectiveness, or marriage issues, these teachers got more than they bargained for when they spoke with their student's parents.
I'm currently a 5th and 6th grade teacher. I had a student a few years ago who was a sweetheart, but would CONSTANTLY miss school. She suffered from some sort of anxiety disorder. I had a real soft spot for her so I did everything I could to help, which included allowing her to leave in the middle of class to call her mom when she felt anxious, allowing her to sit and eat lunch in my room because the lunchroom was too loud and hectic, playing games with her at recess because the other kids didn't want to, etc. I mean I bent over backwards to help this girl. Well, that year this student missed 87 days of school, and that's not including the days she came in late or the days she left early. At the end of the year we had a meeting with her parents to tell her that she wouldn't be passing to the next grade because of all the time she missed (I did inform her parents of this many times throughout the year). Her mom proceeded to rip me part for not teaching her daughter enough, not giving her enough work to keep her motivated, etc. She would not even think about the fact that if you added up all the time she missed it would be close to 100 days of school. I still to this day don't understand if she truly didn't get it, or was legit mentally ill to think her daughter would be doing well while missing 3/4 of the year. (Source)
