That's great JustForUs! The only time a man ever came up to me in a supermarket, he was really creepy and followed me around, and I had to leave before buying everything because I was afraid of him.

I'm glad to hear you had a better experience!
The funniest experience I had with a random strange man was right after New Year's a while back, when I was walking around town on my own (not in Providence, this was in Long Beach, CA), wearing a really low-cut shirt (I am pretty buxom and tend to attract sleazy comments), and this man walking towards me said as he passed "Happy NEW Year!!" in this hilarious tone of voice. That totally cracked me up!
As for a

moment . . . the first thing that's coming to mind actually is when I spent the summer in Livermore, CA (near San Fransisco), a few years ago, my boyfriend came up to visit me and we went in to the city together. I have this vivid memory of sitting on the BART with him being like

!! We had a semi-LDR for a long time (2 years), and that was one of the happiest visits I can remember.
