Yeah, but I never said "no way it's happening" in my initial post (although that would still be an acceptable answer from the DM). It seems like you didn't really read it, or you are combining my post with someone else's and responding as if I'd written both.
Again, you seem to be mixing up my response with someone else's. I never talked about "working together to make something work" - that was the troll.
However, I generally do try to work together with the player, but not always. There are some races that simply don't fit, or I'm simply not willing to deal with. That's my prerogative as a DM.
