Seeing this photo reminds me of a time a bunch of years ago when a friend of mine, in the same conversation, was gushing about a new relationship she was in and also mentioned her favorite flowers: yellow tulips and blue hydrangea. Knowing who he was, about half an hour later he had an email in his inbox informing him of this flower preference. He would have known me by name, but likely not by face.
Four days later, 10 p.m. on February 14, I got a phone call: "It was YOU!!!!!!" Well, yeah. You unwittingly offered up actionable intelligence, I was a nice person, and he would have been an idiot not to get in touch with a florist so you could be the envy of a bunch of your coworkers.
I most certainly got an invitation to their wedding.
