Hi,
They will treat you like a child even when you're 50. Parents have that way about them.
You hurt their feelings with whatever you said and made them defensive. You may have to apologize and let them know that you do appreciate them as your parents. Try giving them a greeting card or writing out a letter to them telling them what you do like about their parenting.
No matter how wrong they may be in any situation-you have to talk to them with respect when you're living under their roof.
If someone were to say to you "Rainstorm, you're always putting me down and you don't care about me."
How would that make you feel?
Can you describe how you feel so that it's not so hard for them to listen to? Instead of talking to them, maybe you can write what you're feeling so you can take your time and think of what you want to say and word it in such a way that it's not going to insult them.
It's the only thing I can think of.
Good luck with this. PM me if you want.
