But when it does, it gives me a spring in my step for the whole day. Not my normal commuting car, but I'm driving my car to the office this morning, and crawling in traffic on what is normally a 3 lane high speed road (50/301 for those in the Annapolis area). I hear a slight beep to my right and look over, and the driver of a blue Durango is gesturing, I roll my window down and get the "500E?" question and a big thumbs up. So I give him a big nod and a smile and say thanks. And then traffic moved and that was it. Love it when that happens.
