I’m not much of a roleplayer, and don’t really care for RP-ing. If a friend asks to roleplay a scene with one of my characters then I might oblige, but it depends on my mood.
I am a writer and novelist, and one who prefers to have control over a scene and interactions between characters, something that is drastically infringed upon while roleplaying. It can be fun, and it does provide insights into characters that I wouldn’t have otherwise had, but it never really held an appeal to me personally, and the few times that I’ve done it have been at the request of others.
