My moment of realization: Yesterday I left my bank card in the slow-as-can-be ATM. As I was walking down the street, the wholesome-looking teenage boy who was with his kindly-seeming mother who was in line at the ATM behind me ran up to me and yelled "mister, you left this."
I immediately remembered, and yelled "oh god damn it!" purely on instinct.
And then I realised...
I was telling this an Australian female friend who had this story to tell.
I was in a bar in Boston watching the Superbowl playoffs, when some dude yelled out "aww, shit!" and was immediately told off by about 3 other dudes to "watch your language, there are ladies present!"
Oh, my poor delicate female... ears? I didn't get the chance to tell him that I'm Australian and therefore immune to his adorable American swears, but it was temping.
