I have to agree with Girly.
My church sent 2 buses of volunteers to the area LAdyL is talking about, this week. Because it's, you know, an emergency.
I'm not sure I understand why folks are downplaying one of the largest storm events to hit the area in decades. Yes, guys, the current situation there is an emergency. It falls under "massive act of God" and is pretty much a text book example of the definition of emergency.
We all have moments where we volunteer to help, and realize later we didn't really mean it and regret offering for whatever reason. But that doesn't mean the other person doesn't have an emergency- it means we offered something we weren't willing or able to do. A friend of mine once offered another, pregnant, friend a vague offer of "I'd be happy to help when the baby comes! Call me for anything!", expecting to get asked to go over and make dinner or something. The baby had problems at birth, and ended up severly damaged- and my friend got a call a few weeks later to please come over and help with a complex medical treatment once a week. She had to sheepishly admit she had no ability to give that kind of help, and had not meant that level of involvement.
No one is saying LadyL is wrong- she can certainly, politely, let her friend know it isn't happening for any reason or no reason, good or bad.
She has the right to say no, absolutely and totally, but her friend has the right to hear "I was just offering to sound good, and didn't really think you would ever need to do it".
This is a real emergency, the kind most people would specifically think of when a friend says "If an emergency happens you can stay here." The friend was in no way wrong to ask because he was told it was ok. It's a shame it just got awkward.
