Does it make a difference to whom? You? Them? IMO, i try to be kind to everyone I meet. No matter what their circumstances in life. When I was still active, I would have conversations with Mormons and even take some of the literature they offered. I remember how nice it was to have a decent conversations while out in fs, so I thought, ah, why not?. When it comes to a witness, what other posters have already said is very true. You'll never be but a nice "worldly" person who'll be destroyed cuz you don't go to meetings and try to live up to the expectations of the GB. And most of them will be nice to you, as long as it is within the social set-up you interact with them, ie: school, work, neighbors, etc. But, never on a personal/friend level. It's all superficial.
