Lifeboat

I'm going to be an ass about a preparedness issue here and I'm not going to hide it behind a cut or a friendwall, because it's something a lot of people need to see.

If you are talking about preparedness and blithely tell someone, "if everything goes to hell, I'll just come to your house," here's what you're really saying:

"I'm too lazy and apathetic to spend any time or effort or money on preparations myself, but when everything goes to hell, I'll come to your house without anything useful to contribute. And I'll expect you to make room for me in your lifeboat and split your limited resources among more people than you'd planned and budgeted to support."

If you're planning on showing up unannounced on someone else's doorstep, show up with skills, supplies, gear that will make you a welcome (or at least tolerable) unplanned addition to the team. Otherwise, you are a net liability for everyone's survival.

(Obviously, this applies far more in situations that are true survival crises than in weather-related inconveniences.)
