>>22880631i had a similar thing happen
i was 11 and under a blanket with my redhead cousin, we were laughing and moving around trying to get the blanket to stand on its own like a canopy
her older brother walked in and i think he thought the same thing
none of us ever spoke of it again though, he just walked out
i wanted to explain what happened but i figured that would make it weirder so i never did
