The problem is that, if things get rough, they will remember your advice and assume that you took your own advice.
Therefore, you must have stuff put away. They will want a share of the stuff that they believe that you have.
That could get serious.
Yup but if things get that bad and they might for a few months, then it would be a good idea to take in a few to help guard things. But don’t show up empty handed with nothing to offer. I’m well stocked and could last 6 months, plus I live right on a bay so I can fish, I have a large garden, a fresh water well and 2 wood burning stoves for cooking. I do need a little more ammo, I have been putting that off for some time now awaiting for a sign that the time has come to spend some of my cash reserve.
