I'm sorry, but I can't be friends with you anymore. You know why.It's not from anyone I know, so I'm pretty sure I'm not being dumped by a friend or even a casual acquaintance.
So I replied.
I'm sorry. Who are you?I doubt I'll get a response, but I'd like to think I helped whomever it was intended for get a bit of a dig in. If not, well...really, who the fark are you?
