Sorry boss, I'm telling you this a bit last minute and all, but I'm afraid I won't be able to participate in this. I'd really like to, I even have a character I'd particularly like to write, but I think I'd only go as far as that. It's really not that I'm not interested or that I find any of your RP's boring, but I'm getting busy again and I'd hate to invest time into an RP which has such involvement with characters in the story (which is amazing, seriously!) only to leave it later.
I really hope I can find time to write with you again some time, when life affords me a bit more free time!
