Girls, I gave my sister a wedgie. Was she right to attack me?

I was watching TV with my kid sister today when she bent over to reach something. I took the opportunity to grab the back of her underwear and pull it to her shoulders. She screamed, but it was hilarious.

Later in the evening, I was changing a light bulb in the hallway when suddenly I felt something nail me hard in the balls. I looked down, and saw that my sister took this as an opportunity to sneak up and knee me right in the nuts. I dropped to the ground holding my berries, as my sister said "Now we're even." I rolled around on the floor for a few minutes, telling her how crappy it was of her to attack me there, but she insisted that it was a good lesson in not giving wedgies.

Okay, maybe she was right to attack me, but going for the sack was too far. I don't think I deserved it. Do you agree?

I warned her that if she attacks me again, she'll be pinned and given wedgies until she apologizes. Lol.
