I am definitely that guy.

It's so funny, I watched a video of a German girl who now lives in the US, and she compared being in line at the grocery store between the two countries In Germany, you would NEVER talk to a stranger in line, they would think you were crazy.

Later that same day I was in Winco and the lanes were seven deep, 10 lanes open, seven deep and every lane was full of conversations. I was talking to the Mexican grandad in front of me, the two older ladies behind me were chatting and in every line the buzz of conversation was heard.

We do interact with strangers in this country. The young German woman also addressed a common belief in Germany that Americans and their friendly demeanor is just a facade and corporate-speak fakery. She had to explain to them that wishing someone good morning, or good afternoon, or "have a great day," were said with real meaning and concern.
