Most people can't...and thus keep on staring making a lady uncomfortable.....as i'am in the corporate sector and have to deal with women daily, i have trained myself to look at the face.....according to me, staring at a woman's top is a social gaffe which we all men should avoid!! As far as the popouts are concerned, well, it can get a bit too much......if it gets too much, God has given us men an outlet to release those pent up emotions, isn't it:)-
