Do they have gas or judgment?

Countless times I run smack against this “look” by someone who, I thought, was asking an authentic, caring question of, “How are you?  How are things with your Mom?”  I thought they truly wanted to know. But when I began answering, not only did their eyes glaze over, they’d check their phone.  When I was in the process of answering their question, I couldn't tell if the expression on their face was judgment, boredom or gas.
