The Sept. 11 attacks happened 11 years ago, long enough for children of those killed in the tragedy to grow into young men and women, perhaps long enough for families to move on (even though they're unlikely to ever completely heal).
But the terrorist attacks haven't been so long ago that Americans and others around the globe have figured out the "right" way to grieve. That's because, of course, there is no single right way.
Some people have chosen to avoid the media this week -- newspapers, social media, television, any talk at all about the attacks -- in a bid to escape the horrible images that force them to relive the day.
Others have drawn closer to some of those media in an effort to honor the dead and to remember, taking pride in the nation's ability to rebuild. Along those lines, a photo gallery featuring images taken by Associated Press photographer and photo editor Mark Lennihan shows just how much the damaged area of New York City has changed over the decade.
