I think we've chatted about this before, but yes.
Mrs. Milepig's first INTL business flight was a surprise b'day gift. By a series of miracles I managed to keep it a secret until we stepped on the plane. It was a UA 767 row 5 (with the old style seats where that row had like a mile of leg room). I stopped and said "here" and she first went sort of "I don't even know how to behave". Within 5 minutes she was playing with the controls, had ordered up a PBD and was investigating the IFE. It doesn't take long!
