While in general I'm all for education I also can't see myself handing out a flyer to family. Nor do I want to be subjected to their laundry list of ailments!!
I figure if they are interested they all know how to google and can certainly ask me questions if they are curious. Other than that I'm pretty sure it isn't on their short list of concerns.
We have fairly good boundaries as a family so I don't offer up too much information regarding MS but I also don't ever feel obligated to do more than I am able to out of peer pressure even before MS.
