I'm going to shred the letter my mom wrote to my dad.
Why are you trying to stop your mom from contacting your dad?
My parents are big mouths. I feel nothing but contempt for my mom's letter.
It's wrong to destroy property and especially property that belongs to your family members since family is supposed to look out for each other. Even if you have an issue with your parents, you shouldn't destroy the letters that they send to one another as it will negatively affect their relationship. You should try talking with a therapist about your negative feelings towards your parents to help you resolve those issues and be less destructive in your behavior.
Nah, you can just shut up. Your opinion doesn't matter to me.
If you have a problem with the letters that your mom wrote to your dad, don't you think it would be better if you just talked to her about it? If you shred the letter, it will probably just lead to more problems.
