Well, Kim - that's just it. For me, that level of reduced interaction was shrinking into myself. When I'm comfortable, I am talking to everyone! No one is ever left out of a conversation. I am a social animal. Why do you think that they fly me - our company's über-geek - to CES? Because I can not only speak fluent geek to the technical elite, but I can usually charm the masses better than our marketing weasels. Our PR people (heck, even our CEO) basically lead the people to me, step back and let me go!
A long day of walking, yes. I can comfortably spend all day clicking around the tile floors of a mall carrying multiple shopping bags in these wonderful shoes. All day trudging through airports with my laptop bag, purse, and a large suitcase with heavy devices (and not a few clothes!) that has the older tiny wheels? Not so much.
