I don't think civility is gone, but I think you have to seek it. I've noticed a lot of the same things that the above posters have mentioned. It's amazing what good grooming can do. This morning I got up, showered, washed my hair, and put on make-up and a nice sweater. While waiting for the bus, a young neighbor (in his twenties,) came up and gave me a hug. A lot of these young boys do that when they see me on the bus. It's fascinating. I just smile and say "hi" to them, and they light up. I think that they don't have the home life that many of us did. My mom cooked a delicious dinner every night and kept the house really clean and organized. There was plenty of food, and we always had clean clothes. That's not happening anymore in most homes. It seems like a lot of these young people respond to kind of a "mom" energy with me. I ask them how things are going and encourage them. I tell them what talents that I see in them. I also think that many many people are addicted to alcohol and/or drugs now. That usually makes people antagonistic and difficult. Exercise is a great mood enhancer, but many people don't do that anymore, either. They're so plugged into their electronics.
What I've done is to make a conscious effort to be friendly, happy, and kind to each person I see each day. It's really working. I had a 23 year old guy on the bus today offer to lift my bike off the rack for me. He was really sweet. He was reading a book at the bus stop, and we had a nice conversation. I told him I didn't know people his age read books anymore. The bus driver smiled and laughed with me as I got off the bus. He was very easy going and well mannered. To me it feels like people want the old fashioned interactions, but not everyone is initiating them anymore. Our society is kind of aloof. I took a train trip downtown a couple of days ago. Several people at Union Station offered to help me as I was lugging my bike up the stairs. It really made me feel good. I also chatted with several bicyclists on the subway. We all had our bikes crammed into the bike car. They were real friendly and open. It's giving me hope.
But yes, I see what you're saying. It's out there.
