I heard this from my mother recently. One of her co-workers had taken her bratty son to pre-school or pre-kindergarten (what's the difference?), I guess, to just kind of check the place out. The kid huffed, said,
"I'm not staying here!" or,
"I'm not going to school" and spit on the teacher's desk. From there, he was put out in the hallway as sort of a time out.
Fabulous - he got thrown out before he even started. I'm sure the teacher(s) was glad to have weeded this brat out before officially having him attend. I suggested that she should consider home-schooling the brat because teachers don't get paid nearly enough to put up with even a fraction of the shit they deal with regularly from little bastards.
