A little girl kept staring at me on the mbta so i kept smiling back. After about ten minutes she whispers "excuse me...do you work for S.H.I.E.L.D." and point to the shield pin on my black leather jacket. I smiled, nodded and put my finger to my lips and said "it's a secret." She got very excited and bounced in her seat for a few minutes. As she got off the train she says "go kick those stupid octopuses' bums" it was so precious and the best moment of my life!
