Have you ever kissed a someone just because they were y and within kissing distance?

I have this chick I work with. We talk talk and joke alot. She is really hot. Well one night we got off from work and were talking by our cars and right before she got in the car there was a weird pause and eye contact. We joke alot but I can't say there's any ual type flirtation. I didn't kiss her and I won't but I wonder if she was thinking the same thing I was.
