As I look down through the thread titles, I'm reminded of a time when I visited my Grandparents when I was in my twenties, and they had friends over. I just sat with them for quite a while listening. They finally asked me if something was wrong, since I wasn't talking with them. I told them that since I didn't have anything physically wrong with me, I just didn't have anything to contribute to the conversation. Everyone broke up laughing!!!
Although I look at this in a humorous manner, it does bring back warm memories of those long ago times.
