Maybe that's a cultural difference. How old would the kid be?
The kindergarten my younger brother went to like more than a decade ago didn't have backboards and stuff, at least none that I remember. Kids would learn to read and write in the "0th" class of the primary school by the age of 6.
Can't go to the bathroom more than once per class? OK, I'll just stand outside the classroom.
I have a story that kinda fits! Never shared this before, but I'm sure many people have experienced something similar....
