Just had a funny DB moment. Did I handle it right?

I'm not longer looking for hugs / affection when I pickup the kids. Nothing.

Tonight my wife said "Love You" to me as we were going out the door at her work. I smiled and said good bye. She said it again. "Love you". So I said it back then.

Is there a Right or wrong here?
