In the fourth grade, I decided to do something to someone for April Fools day. My friend was standing up at her desk and her chair was behind her. I got up and moved her seat back a little further without her noticing. When she sat down, she fell right on the ground and to my surprise, everyone started laughing at her. From across the room I yelled "April Fools." I felt bad because everyone saw, but she wasnt mad, just embarrassed.
