On the last day of the year, what have you left unspoken, unwritten, unshared?

From the NY Times:

Last month, Illegal Art, the New York-based public-art collective, placed installations around the city and invited passers-by to offer a few last words. Here is a sampling of what people left behind. The words remind us of the things we should have said, but didn’t, and maybe the things we said, but now regret. They also remind us that with a new year only hours away, there’s still time to get in an important last word before the clock strikes midnight.

Check out what people scribbled down, from the simple (“I forgive you”) to the enigmatic (“I did remember.”)
