When I was about 6 my brother found a large egg shaped rock he told me it was a dinosaur egg and that because I was a girl I could sit on it and it would hatch and I could have my own pet dinosaur. I spent all after noon sitting on the "egg" then brought it in the house sat on it at dinner, put it in my bed slept with it and brought it in to school and put it on my chair to sit on it there, at which point my teacher asked what I was doing. I enthusiastically explained when she told me it wasn't really an egg I got mad and threw it on the floor which broke it revealing it was actually a crystal I kept it and still have it.
