From what I can tell from the videos I've seen, that was the clock time when the first bomb went off at the finish line of the 2013 Boston Marathon. Many runners view Boston as the ultimate goal race. Although my best times would never qualify me for the event, the time the bombs went off were within my best pacing in other marathons.
Those runners were people like me, people I may have talked to or silently struggled along with in solidarity. The people in the stands were people just like my wife, my parents and in-laws, siblings, nieces and nephews, friends, acquaintances, fellow humans all.
There are no words that will satisfy our questions as to why this happened. Three people are dead and more than 100 were injured. In these times that show the worst of mankind, we also witness the best of humanity: Those brave people who rushed to aid those in need. That Mr. Rogers quote is everywhere now and risks becoming trite. But I know how I have felt at the end of a marathon, and I don't know if I could summon the energy to flee such chaos after having run 26 miles without someone's help.
The world can be a bad place if we let it, but tragedies like this can also bring us together. Today, let's remember the people who are suffering and rush to help where we can.
