Do you think I should refuse to give up my window seat on a long flight to a mother who wanted to sit next to her husband and kid?
Seriously? Why would you refuse to give that seat up?
I just don't feel like moving seats.
It's understandable to not want to move seats but you should think about how she would feel being separated from her family. I'm sure if the roles were switched you would like someone to change seats with you.
I really just don't want to move.
I really think switching seats would be the right thing to do. It's good to do nice things for people and in her situation, you would be letting her sit with her family. I'm sure the seat doesn't mean as much to you as it does to her so you should really consider switching.
