people said please and thank you.
we held doors open for each other.
gave up our place in line to the person who had fewer items.
smiled.
waved.
said "keep the change".

Don't wear a hat
Usually do say please when I'm ordering at a restaurant, and say thank you.
Don't go shopping that often for a lot of stuff, but I have had people do just that when I've had one or two items. Which is great.
Smiling and Waving - Normally you only do that with people you know. So thus the problem becomes one of a lack of community. It is kind of hard to know a lot of people when you are busy chasing the almighty dollar, trying to get out of debt, because the government is confiscating your money, and then bills eat up the rest.
Well, now a days, saying keep the change on a meal might be insulting if the meal is $19.38 after taxes, and you pay with a $20, but normally I tip 20% - 40% (I've also tipped over 50% a few times in the last year, good service deserves recognition)
What can you do?
The key to rebuilding America is not government, the key to rebuilding America is to re-unite the communities and get people to talk again.
Though it's interesting. Was at the bank today and stopped to talk to the banker that I know. Just saying hello, because I was there, and had spoken with him before.
Though I do like the lay out at the branch. They have the bank managers stationed in the center so you can see them, and the counter to make deposits and speak with tellers is off to the side.
