Jean, I've thought of your thread on and off all day. I know it was directed at survivor's though.
My Dad doesn't know he's had a stroke (let alone 2) unless you tell him. He will forget in a few minutes or not really comprehend what that means. My Dad is a great guy, and has never met a stranger. I haven't noticed anyone looking uncomfortable around him, although he is sorely lacking in friends and family now.
As far as if I am embarrassed? I know that wasn't part of the question, but I'm throwing it in here as a bonus. I have taken Dad many places, pushed people out of the way so he can see, kicked rude self-centered souls accidentally in my plight to get him where he wants to go. In all that time, all I've ever felt was proud. Proud of him and all he's survived. Proud of myself for being with him at this point in his life. I dare anyone to get in his way.
