How about I spam a friend about a d&d game?
Oh my, is there a reason why you have to spam him?
I have to be the solo star of all of his D&D characters.
You shouldn't spam someone over a game. Your friend will block you then you won't have anyone to play with.
He should block me since he doesn't want to be a part of my characters.
But that will mean you won't be able to play with him and have fun. Just stop messaging him so much so he doesn't get annoyed. He will respond when he can.
