Do I really need to care about my parents' opinion every time? I think no.
Why do you not want to worry about your parent's opinion?
They have been so stubborn about telling me what to do for so long.
Your parents really care about you, so it makes more sense to try and hear out what your parents have to say to you.
Nah, I can live without them. They just want to control me and my life.
You should talk to your parents and have an honest discussion about it. I'm sure they tell you for your own good with only best interests in mind so you should respect their opinion. It's ok to have different view but you're expected to be considerate about what they say.
