London rocked by four blasts.
Whatever's bothering you probably isn't that big a deal.
If you're even more out of the loop than I am, then, well, go to Google news and search on London and you'll find out that three Underground stations and a bus were bombed today.
To borrow Wil Wheaton's phrase "send some mojo."
My Mom would probably suggest prayers.
In any case, take a moment and send them some goodwill in whatever fashion you see fit... even if you're not one of the persons wondering if friends, coworkers or family are among lost or injured.
