Not counting my own family, in the past week I had two quick positive experiences while wearing superhero t-shirts. The first was simply a couple of young boys who seemed be giving their father a bit of a hassle in te parking lot. One of them saw my Captain America shirt and pointed it out to his brother and father. That was it, they then quietly walked with their father into the store.
The second experience was also at the store. I was walking down an aisle and a toddler started smiling at me. I checked behind me to see if there was someone else behind me, but no one was. I smiled and waved, and he waved back and gave me an even bigger smile. It wasn't until I passed that I was wearing my Batman shirt.
I like superheroes for a number of reasons, moments like these are just icing.
