As an RN whose passion was educating patients, families and fellow coworkers I was never hesitant to tell anyone about what MS is. And as far as the statement about 'that gravy train', they don't deserve an answer if they say that to you. I do get statements about why I have a handicap placcard. I just tell them that if they are willing to trade me their worst day for my MS that it does come with the sticker to use. I'm just forever grateful that all of my family understands. Of course most of my family have some ind of auto immune disorder so all of us understand anyway!
