I have found all of the above to be so true. If, (key word being if) someone asks about MG or how I'm doing, I see their eyes glazing over before I can complete a response. Spouse, adult children, friends, neighbors - basically all the same. I'm still waiting for at least one person to say "hey, tell me more about MG"
Much to my surprise - I've even noticed it at our local support group - whatever I share, others interject and interrupt to let me know about their MG. Disappointing.
But, I attribute others' behavior to just human nature and have slowly learned to roll with it. Very slowly.
