“I wonder how many of them are still choking down dehydrated beans.”
Had some yesterday, as a matter of fact. ‘Stocking up’ does not make one an “nut”. Those who buy their groceries daily are the fools.
That kind of depends on what you are stocking up for. When you start resembling Charles Manson and his followers (doubtless you are more groomed and less psychotic) stocking up for the social chaos of "Helter Skelter" you can pretty much be labeled a nut.
