Many years ago in TATL coach (LH ORD-FRA) I was in aisle seat with two empty seats between me and the window but about a minute before take-off the FA arrived with two unaccompanied minors on their way to India. I learned that dad was trying to finish his thesis and they were being sent to live with their Uncle and Aunt. I feared the worst but shortly after dinner they announced they were tired and (in the pre-strap yourself in just in case there is turbulence era) one sacked out on their two seats and the other set up some pillows on the floor and they slept until breakfast. I have never had such a quiet evening in an aisle seat (no fidgeting, snoring, climbing over me to the bathroom) and [my complaint] probably never will again.
