Hmmm, say your sorry? Or say, Please forgive me i didn't mean to!
He's giving me the silent treatment for not liking his friend that is literally a slut :-
Oh, well then i've got use the sentence! Tell him this. "Don't give me the silent treatment because your friend is a slut and you have a no reason to give me that treatment when your friend is a bad person!"
I tried telling him that ;-;
Hmmm, Try roasting him! (No literally roast him as in put him in the oven and stuff) Or use the sweet talk ;3 Or maybe just say your sorry about not liking his friend?
