What is this? "Take over" people's characters? Look, if you've got to be away for a while, just say so. It's perfectly fine. If you don't care about your character enough to be involved in what happens to them, that's an insult to all the effort and enjoyment people are putting into this rp with their time and creativity. I get it. It's just an rp thread. People come and go and sometimes people have to take breaks. It's only here because it's fun and people have time. If you don't have those, then you're not in this. That's life. 

So make a decision. Stay, leave, take a break, or simply vanish off the site, but don't "offer" to dump your responsibility onto someone else.
