Gravitational Forces

Hello people of the Internet,

So, today during our music class, we were just waiting to play our instruments. Our teacher was just about to let us play when this guy just fell out of his seat. He then had to go up to the teacher and explain what happened.

He couldn't look up apparently and he said that he took a breath and fell off the chair.

Later, after lunch, we were lining up to go to our class when I asked how he fell. He replied that he choked (I don't know what). It was really weird.

Thanks for reading,
