I laughed at a kid that was having a seizure in the middle of class
How would you feel if you were in that position?
Actually I'm used with all this. So it didn't affect me at all.
It still seems a little wrong to laugh. The poor kid was having a medical emergency, you could have helped him instead.
It's medical issue and I am not a miracle worker and also I was studying.
There might not been a lot that you could do but laughing at them is mean. People will think you are a jerk and not want anything to do with you.
