Re Deepblue:

Thanks for your reply.

You're right that my mom and I do really like. We are both subjective. Most of the time, we have opinions opposite to each other. Or we pre-assume what the other is thinking of. That makes things gone worse and leads to conflicts and agruements.

I think I should try to change myself, to be not that stubborn on my own points, but to listen to my mother's words.
