Laughing at Angry People
When my teachers yell at me, or my sister even I can't help but laugh. Not giggle, but sometimes laughing so hard my stomach hurts. Most of the time I can't help it. The look on their faces is hilarious when they are mad, and usually it just gets me into more trouble. Is this normal?
I guess because you probably don't like the people yelling at you very much... or you don't respect them - something liek that.
This suggests to me that you are either of such descent or your brain power is lacking quite considerably. Most probably the latter.
