clueless

I was having an ultrasound done today and I know the tech cannot say anything about what they see and that's understandable, but my question is, if you see something really bad how do you keep a poker face?

be proud of the adult you've become?

And if you have have you seen it in more than one location. I was wondering if the story line is the same everywhere or is it location specific? Ex. In vegas , vegas flooded and the golden axe was found in a wall at graceland.

On a flight from St Louis to Vegas and back I was seated in the row behind the exit row in the middle seat. On the way out in the exit row was an asian man with his wife and 4 yo son. He obviously spoke minimal english and the combined weight of the three of thm would barely be 200lbs. On the way back Same scenario. 2 teenagers and an elderly man with a walker. Me in the same middle seat behind them. I am 6'4" 250 lbs speak perfect english. When I asked to be switched I was told no. These are the seating assignments.Yet the 4 yo was removed for takeoff and landing.Whenever I fly international I am asked if I would mind changing to the exit row. I need the room but also am capable of opening the door. Is there a criteria for who sits at the exits on domestic flights?

If is customary how much?
