I'm going to be cold to my parents
Why be cold to your parents?
When i was a child they did not pay much attention to me.
It is understandable to hold some resentment towards your parents for the way they treated you when you were young. But things can change as everyone ages, maybe now they can be more receptive towards you.
I would rather be cold. I go to college now and am fine without their attention.
Try your best to not treat your parents poorly. Your feelings are completely valid however, and letting your parents know that you feel that way is something you should take time to do. Holding all that negativity in is not something you want to do for long.
