I'm thinking of disowning my mom and dad over a job.
Why would a job make you disown your parents?
They don't want me to take the job even though I really want it.
It's good to take your parents' advice into consideration and to keep a healthy relationship with them. At the end of the day though, it's your life and you should live it how you want. Try to talk to them about how you are feeling.
Whatever. I don't care.
I'm sure if you tell them that you really want the job and explain to them why, they will eventually come around. Even if they do get upset with you for taking the job, you don't need to disown them. I'm sure they will eventually get over their anger and want you in their lives.
