I've often heard (well or saw negative reaction) from strange girls, something like:
Why d'u look at me in SUCH a manner
Or
Hey, guy, stop gazing me
etc.

I always responded without reflecting
Baby, u know, it's SO difficult not to look at beauty
And it so, sometimes it's so difficultly to control yourself and not to look at the passing by princess when u see, that she does not go, but slide, a warm southern wind blows light summer dress... her lovely smile causes the most pleasant feelings and emotions...
And it's even unimportant, that it is not yours, that will never see any more: such thoughts appears - in fact someone or something has created such beauty, as the artist creates a picture, the designer - the machine, the writer - the poem... And all this as though only to please an eye.
It is impossible to avert from the beautiful!!! Excuse, if I stare at you too brass, but there is just craving of any person for affinity!
