Mary thought a lot of herself. There didn't seem to be any cleavage to look at....perhaps the ogler was on a nipple search?
It doesn't have to be a lot. The mere fact that there is cleavage is enough to draw the male eye like a magnet. That guy is old enough to know that once you get your peek, you got to pull away quickly or else you may become mesmerized to the point of embarrassment. We've all been there.
