Welcome to the forum Jen, I see that you have already met a few of us. AS you can tell, we are a friendly bunch. You won't find talk about looting, stealing from the less fortunate, or cannabilism here, if you do happen to see it, let one of us know. We'll be on them like white on rice. We don't put up with rubbish like that.
Don't try to change the minds of those around you if they aren't inclined. By continuously talking to them, it will stick in their mind and when the world goes to hell, they'll remember who to go to because you have food and a means of living.
