I get along with Bruce because he's my friend, if we all got along with the same kind of people the world would be pretty boring. [Which is a safer topic than talking about Bruce.]

Would it help if you gave him another name? Calling him 'Queen' or 'Arrow', instead of your best friend's name. I think if you manage to set them apart in your mind it will be easier. [Says the guy who's pretending there isn't any differences between his Bruce and this Bruce. At all. Really, the only reason this is working for Kal is because Bruce actually wants to pretend to be him.]
