Keeping in mind that I still attend the sporadic meeting here and there, so I know many of them in the area where I live, when I see them in stores and they don't see me I try my best to avoid them.
I never go out of my way to greet them or make conversation with them. I'm sure in their mind they consider me 'spiritually weak/borderline apostate' so they could also care less about going out of their way to talk to me or greet me.
It's a mutual avoidance going on.
