15 years after. Not clear blue. But gray and muggy. And quiet. Said Joe Quinn, brother of Jimmy Quin, killed in the North Tower, at today’s ceremony:

For one day, just one day, shut off your television, power down your phone and go outside. Say hello to your neighbor. Volunteer, Engage with your community. Do not sit on the sidelines. Be the inspiration we so desperately crave. 

And then tomorrow, by dawn’s early light, put one foot in front of the other, and do it again. Be the unity that this world needs.

Only if.
