September 11th-Just another day?

I was struck the other day when I heard an ad on the radio talking about a sale that ends on "September 11th." It was said in such a run of the mill fashion and I thought to myself...I guess 4 years is how long it takes to get back to "normal."

And then this morning's attack in London. It seems like the Brits have a big choice in how to respond--and I hope it is not like the way the Spaniards did.
