What do you think about me planning to destroy my sister's confidence and thus kinda ruin her birthday party?
What would you do to destroy her confidence and ruin her birthday party?
I will tell her she's the most inferior and useless out of my siblings
It is hard to get along with siblings sometimes but you shouldn't ruin her party. She might never forgive you for it.
I don't care. I'm gonna ruin her party and make her not want to visit our parents.
Does this seem nice to you? Your sister loves you and is your family, you shouldn't want to ruin her party. Take care of your family or people will think you're weird.
