I figured that's what you meant, but I wanted to just clarify and whatnot. I know you aren't advocating just dropping threads willy-nilly. It's true that there are threads that just won't go anywhere, other because one or both muns aren't into it, timing kind of derails it, etc etc.
But yeah, I agree. Everyone's super good about backtagging, but sometimes it's not necessary to tag back every single thread. I know that some people (myself included) can feel guilty about dropping threads - but there's really absolutely no need to be guilty about it. Life happens, rp is for fun, and some threads just aren't going to be as long as others.
