I usually ignore that or head it off to the best of my ability if I notice it soon enough. But that is pretty much why I mentioned it. It seems there's a pretty good correlation between wondering if an rp's going to die and then having it die. 

Sometimes, this might be reasonable simply because it actually is going dead and you're hopeful but it's not turning out. 

Other times, it's more likely a spiral that could have been avoided through the simple expedience of a bit of extra patience and not asking about it, so no one else winds up worrying or feeling pressured into posting. 

Sort of like how just about every time someone says things couldn't get any worse in a movie, you start expecting rain....
