Why does this make me cry?

<p>Before Christmas I took my son onto the floor of the New York Stock Exchange.
They have POW/MIA flags hanging on the wall in the “Garage”. Maybe the most patriotic institution in Manhattan.
He was wearing his SDBs.</p>

<p>Traders clapped and came up to him to shake his hand as he went around the posts.</p>

<p>They wanted to know about his Academy experience but he was more interested
in learning how to scalp trades on the floor.</p>
