Oddly, I cry at TV commercials at home but I have never cried on an airplane. Maybe I have the opposite syndrome.
Still, the complete lack of control. Putting my life into the hands of a couple of pilots (and the plane’s maintenance crews) forces me to evaluate my life and say a prayer before each take-off. Not a bad thing, I guess.
If you’re ever on Delta, get the Biscoff cookies. They help.
