Their complaining about the size and weight for their school bag runs along these lines:
“Stupid bag why can’t it be like a T.A.R.D.I.S. and be bigger on the inside then on the outside. Why can’t I have grav gun to carry it to school? Or better yet have a school bag made of sapient pear wood, but it might eat the teachers. Or why can’t
school bags be bags of holding or why can’t I cast a Mobiliarbus spell on it but I would still have to walk with it. Why can’t there be portals from home to school,
that way I wouldn’t have to walk with it and I would never be late or get rained on. Life’s not fair!”
This was the rant at lunch time when he came home and was switching his books for this afternoon classes, I had to try not to roar laughing.
