That's intereseting because when it comes to my folks...mom is the hermit, dad's the socialite. He's told me he feels embarrassed when he goes to things and my mom doesn't want to go. Of course in their situation many of his "events" are religion oriented at the church...even if it is just fellowshipping....but my mom is not religious and is not comfortable in that environment....never has been. My dad has in the last 5-yrs or so rediscovered religion and like everything else has thrown himself into it overzealously....so right now every activity for him revolves around the church.
I'm sure that's not quite the case with you guys. I just find it interesting that he's embarrassed that she doesn't usually go with him....when he's doing something he knows she doesn't like. It's not like this is news to him.
