Tenant saw me in Wal-Mart and didn't try to hide

I was at Wal-Mart today looking at the sore throat lozenges (yes, I just got over the flu not too long ago, it's been -3 degrees F here for the past several days, and I'm still dealing with a sore throat).

So I hear a "Dawn, Dawn" and look over and there's my tenant.  She says hello and I say hello back.  The gentleman she's with asks who I am and she says, "That's my landlord."

I'm grateful that I have tenants who, when they see me outside the normal landlord/tenant context, come up to me to say "hi", versus running away because they owe me rent and don't want me nagging them!  :)
