Flirting?!.... Me?... Not Even

Was driving to the doggie park yesterday evening and the car next to me at the traffic lights was driving my future car aka dream car an all white Audi SUV❤.It was a frikken sexy vehicle anyways the driver of that car saw my dog and complimented me on my dog when he saw her through the window. We shared small talk while waiting for the traffic light to turn green . I was gonna say "Nice Car" but chickened out and that kinda sounded like I'm flirting which I didn't want to come across as. Hmm harmless flirting wouldn't be the worst thing in the world.... Overthinking as usual
