It doesn’t sound like they do.
Maybe it’s my Jewish upbringing, but I can’t imagine parents being beyond upset because their child wants to become a doctor! My parents would have been on cloud nine. If only I didn’t go into shock from just talking about lacerations, who knows.
The OP’s description sent off all kinds of alarms about parents living vicariously through the children without regards to the interests of the child.
We have two kids. They are different from us, and different from each other. They are finding their way we root for them. We paid their way through college and didn’t meddle.
