Your parents’ dream for you is worth hearing. It’s not a contract you signed.

What they want for you is usually made of their own history: the thing they missed, the security they never had, the fear they would rather you avoided. That makes it worth listening to, because there is real information in it about what a life costs. It does not make it binding. You were not party to the agreement, and the world they planned in has partly changed.

So hear it out before arguing, and ask what the worry underneath actually is. Often that worry can be answered by a different route than the one they named. Tell them your version in terms of what they are afraid of.
