Funny Anger...

I have done many funny things, but people usually do not get angry over it. But there were a couple of times when my mom got angry over it. Like this one time, actually a couple of days ago, i asked my mom if she wanted to see an optical illusion. She said sure so i told her to put her pointer fingers out and to slowly move them towards each other, while looking at them. So she did, and when they were next to each other, i grabbed them and hit her forehead, it was a light hit though. she fell backwards onto the wall, and she got angry at me, but everyone else was laughing.
