OMG, the one you heard. Seriously.
The conversation I overheard on an airplane, about 2 rows ahead, was one in which a young teen kept asking her uncle, in a loud voice, "Uncle Jack, when are we going to get to ---?" And, ""will we see ---- when we get there?"
To which her father or uncle replied about the time and, "Yes, we will".
This was said about 10 times before take off, and she continued after landing. We couldnt hear her during the flight itself. I understood she had a type of disability, but most people around her were rolling their eyes by the 5th time.
The only true wisdom is in knowing you know nothing.
