Dreaming in Digital

As Shortbread and I went for a walk through the sunny streets of a busy city, somehow I've gotten hold of two letters folded together and from a friend from anime club. The letters were about how Wafer had told him that I was (in the same terminology) a "whore", and he could not be my friend anymore for this reason. I was confused; why was this happening? Why would Wafer call me a whore, and why would my friend cut himself completely away from me without confronting me first for whether this was real or not?
