I generally treat role playing the same way I treat my sexuality: if it comes up, I'll talk about it. If not, whatever. 

The only time I really actively talked about role playing was with the table top group I joined my freshman year at college (everyone graduated though so I'm alone now, lol) and when a friend and I were still close. Haha, now I'm sad. Oh well.

Plus I'm buddies with some former RP'rs so I bring it up with them if I'm in a particularly good RP.

Then there's this strange relationship with another kinda friend? And we both RP a lot but we never talk about it? It's like a Fight Club thing between us, lol

So Idk. Overall, it's not fun talking about it with people who don't do it in my opinion. And it's hard to find people who do it.
