On a flight from London to Barcelona for the WBTA last year, there was a very loud British family (older mom and dad, 20-something son and daughter) that made an impression on us as soon as they boarded the plane. The mother and daughter were pleasant but very boisterous (the type you really don't want to sit by). I don't think the son ever said a word. They were seated a few rows behind us, so we were treated to their "family dynamics" for much of the flight. Fast forward, and who boards the ship with us? Of course. During our two week sailing, the daughter was quite visible and seemed to enjoy making a spectacle of herself (but not in a mean or rude way).
One day, as DH and I were delivering FE gifts, we stopped to speak with another Disser who "caught" us in the hallway. Just then, the father of the British family comes out of the cabin across the hall. We exchange pleasantries, and he moves on. A few minutes later, the mother opens the door, looking for the father. The daughter then appears, wrapped only in a towel. The mother retreats, but the daughter steps out into the hall to join our conversation. She makes a joke about just having showered and proceeds to adjust her towel, opening it fully at one point. My DH, who was standing directly in front of her, almost choked; I missed the "show", since I was standing off to the side. The mother then came back out and insisted she go get dressed.
For the rest of the cruise, she was known to our family as the "Naked British Girl" or NBG. One of our tablemates was a very attractive young man traveling with his GF and other family. When we shared our story at dinner one night, he knew exactly who we were talking about, because she had blatantly propositioned him! It was actually very funny, and we still talk about her when we think of that cruise. Ahhh, memories!
