Just an observation, n=1; when I moved to Los Angeles to go to school, I was shocked to find that people cancelled plans on me all the time. At first I took it personally, because that didn't happen in the more rural town I'm from. But then I realized: its part of the culture, and maybe its just an attribute of very dynamic urban social networks, where an exciting new opportunity might pop up any moment. So I learned to not get my hopes up, and learned to cancel on others too without worrying about it over much.
When I moved back to rural California, people thought I'd become a jerk. Took me a while to shift back.
