My friend came over to my house. We have two REALLY soft beds, my bro Caleb's and my parents'. She laid on Caleb's and was wearing his pants

(we were making fun of him) and she said, "haha we need to tell Caleb that I'm in his bett wearing his clothes!" REalization hit her quickly, and we ran out screaming together. Then she went to my parents room. She was out of that bett quickly. Can Du guess why?
