What do you think about me telling my sister that she is nothing extraordinary?
Why are you going to try to hurt your sister like that?
I think she doesn't deserve to be happy
I think that you should reconsider what you are going to tell her. It is not okay to put people down like that. It is hurtful!
She's a cunt, who cares about her feelings? Besides, it's not like she cares about me.
Instead of putting your sister down, think of ways to improve your connection. The bond you choose to have with her now will last a lifetime.
