My mom's friend, a frequent visitor to our house, was staying with us for a few nights. At night, I was tasked with giving her a blanket.

I walked over to the guest room, where she was staying. Stupidly, I opened the door without knocking first. As I opened the door, I was shocked to see that she was standing there half-naked.

"Oh my gosh, I'm so sorry!" I said. "I didn't mean to open the door without knocking."
