They said hello, we did not, we both just glared and looked through them.
Might mention - these particular ones were only ever decent to us at the KH when they needed advice on buying a car (i was useful) or when their son's truck broke down and they needed mechanical help (my husband was useful). Plus, last year when we were moving a few blocks away, the wife drove by and stopped as we were outside loading a truck, and she gasped in horror at the sight of my handgun on my side. My KH spy told me that there was a rumor going around that I 'brandished' a gun at her, and that we'd gone crazy.
And we quit going 2.5 years ago anyways and none of them gave a damn.
