OK, I've read better poetry, sure. Correctly spelled even.
But I just like so much how someone would stop and take a moment to express their feelings in a creative way to share with all who pass by. It wasn't meant for me (that I know of), but they were obviously thinking of someone special to them, and I like whenever that happens. Wherever. However. So yeah. I do like it when you loose control.
Let someone know how you feel today, whether by a little vandalism, a real, actual phone call, a skywriter ... you'll know what to do.
