No. I've had lots of interaction with JW's, some family some not.
On my job I work in a large department store in the men's department and several times JW's have come in to buy dress clothes for talks or assemblies. You can spot them a mile away and the language is so familiar . I have many times helped them pick out the right size shirt, pants and the right color tie and gladly take their money! It wasn't that long ago I was doing the same thing shopping for my boys and hubby getting ready for an assembly or whatever, sigh.
I think it's always good to be nice and cordial to people regardless of whom they are, if they want to shun me that's their problem not mine and not the way I want to be.
