Like Megan, I think we get what we look for, too or, maybe what we expect. It is easier to go along with the mass consciousness of watching for things which are wrong/bad/etc. than to make the effort to look for the good and make note of it. A good balance can be difficult. Granted in larger cities it can be a challenge.

We do a lot of driving out here in the West and I can say that drivers seem to be much ruder than they used to be. One really has to practice defensive driving. In stores, etc. most people here are at least somewhat polite, still. Though, if I hold a door for someone and they don't say anything, esp. if they are *pushy*, I will say "You're welcome" as they pass by.

As for the elderly Sikh couple on the bus, my first thought was maybe because of the general anti-immigrant climate I've been reading about, they feel safer not speaking to anyone? Just a thought, meaning no offence to you personally.

My theory is that the more we all continue to be polite, the more likely it will increase.:-) My grandson has learned wonderful manners, not just from his granny, but also at home and school. There is hope for the next generation, imo.:-)
