Try sitting on a 7 hour night flight from NY to Heathrow and a 50 year old woman starts chatting...for the whole flight, at surprise intervals.
She proceeds at one point to mention that she thinks you look like Robbie Williams. And 2 hours later when you're standing in line for the bathroom, you see a small head pop out from its seat, TURN around against the direction of all the seats, and snap a picture of you....with FLASH...in a night flight...
Tell me...how would you feel when coming back to sit next to her. To be fair she acknowledged later what she did, she said it was for her daughter back home to see how much I looked like Robbie...
OH NO it doesn't end there...She was on the small transit fly from Heathrow to Brussels! And sat next to me at the terminal with her senile husband that didn't utter a word the whole trip...
