I was out at REI the other day and had on my Dept of Highland Security "raid" t-shirt (logo on the front, big white DHS on the back) when a gent came up to me and said with a smile "My son-in-law is a colleague of yours." Realizing that he was referring to my t-shirt, I thought to ask the gent what his son-in-law's handle here on Xmarks was when he said "He works for TSA at Reagan National" I smiled, said something about it being a small world and went on my way. Turns out when people aren't paying close attention they see what they want to see. Was certainly good for a laugh.
