And the familial insanity continues...

I was playing a little friendly catching with my little sister when she ran and wrapped the day curtain in my room around herself, "hiding".

"Invisibility Cloak!" I called out, grinning as I walked closer.

And then she unwrapped herself and kicked me in the groin. I fell to the bed. She was understandably apologetic, and ran to get me a bunch of ice wrapped in a double layer of tissue paper for it; I couldn't stop laughing, despite the pain.
