A girl in school said that she wanted to try something. I said sure and she told me to stand with my arms and legs spread and close my eyes. I did and she kicked me in the nuts! It hurt like hell. The girl and her friends just laughed at me. The teacher saw it and she just giggled. When I told my mother about it she just laughed and said that it was the oldest trick in the book and she did it to boys too when she was young. She said that young girls do this for fun and I have to be smarter to avoid it or get used to it. Is this right? Should I just accept that girls can hit guys in the balls for fun?
