In preschool we had a very strict teacher. She used to sit out front and and say "NO BREATHING" And in my class there were 15 students in my class and only 5 left when you would go to leave. You were

literally stepping on kids when you walked to the exit. and there was always a whiny kid going "mehr! mehr! can i do some breathing?" she would say " NO YOU GOT ALL PLAY TIME TO DO THAT!"
