Let me make it clear at the start that I am not (and never have been) a member of The Church of Jesus Christ of Latter-day Saints. So I am writing as an outsider. That being said, I have had several encounters with Saints over the past two decades, and I would venture to say that every one of them has been positive. So, yes, I write as an outsider, but as a friend.
A few months ago, I was working at my part-time retail job, and I had a marvelous encounter with some young Mormons that was the perfect example of what a great witness for their faith they can be.
