I finally look up to a chaperon to see if they're watching this interaction (which they were) and I turn to the little boys and go "Do you wanna try popping bubbles with me?" They were more than happy to join in. We sat there popping bubbles for several stops when they asked my if my phone could do other neat things. I have this camera app that takes multiple shots at once, so I had one of the little boys wave for me so I could show them how it worked. Keep in mind this whole time the parents/chaperons are cracking up and snapping pics of us playing together. All of the little kids in the group waved goodbye to me when I got off at my stop.
It was truly one of those priceless 'only on the subway moments.'
