Grandma’s little stretch
It doesn’t seem like the best use of your flying time to be dodging punches to the face from some quiet grandmother who is simply holding her hands together and extending her limbs.
To be honest, we would much rather read a book or watch a movie than play dodgeball from the row in front using Grandma’s joined hands. It would be best if this guy took hold of her hands and threw them back over the seat.
