Does it sound like he knew I was attracted to him?

I don't know but this is the second time it has happened. But last night, I was talking to a very handsome tall fireman who came into my apartment. I was insanely attracted to him but I tried keeping it under wraps. Suddenly as I was speaking, his face turned very happy, looking at me with a very happy countenance. I have no idea why he looking at me happily. Everyone in my city is grim / serious looking usually. There is a leak in my home and its not fixed. Then he begins talking to me in a very soft, tender tone. Do you think he kinda sensed I was attracted to him?

This also happened while I was talking to another plumber who I was very attracted to. His tone of voice just got super soft while talking to me.
