I mentioned up thread I have a sister named Karen. She and I were on a short trip with a third sister who requires a wheelchair. Travel can sometimes be a challenge and after a full day of driving and visiting a few relatives, we were all getting a bit short on patience and were hungry. As we were about to check in to the hotel, Karen started asking/complaining about something as I'm trying to hunt for a credit card and sister in wheelchair asking the desk clerk about the room and we both stopped and said "Ok, Karen, just a minute" in exasperated voices.
The desk clerk gave us both the stink eye. Remembering this thread, I said "No, that is really her name." We all got a laugh.
