OK! I did the experiment from a females point of view!

I was on the train and there was a guy sitting across from me who was pretty damned attractive so I thought hmmm... Does it work the same way with girls?

So I looked over and met his eye, I held it and he shunted within seconds.

So I smiled and looked around then looked over again and he was looking at me so I met his eye again and after a few seconds he shunted.

The next time I met his eye I smiled and he shunted.

By this time he is smiling to himself but still to afraid to hold my eye. When the other person in the train cabin got off at the next step I met his eye, tilted my head and went "Why are you staring at me?" and laughed.

So he got up and walked over and sat in the seat across from me, introduced himself and I eventually asked why he wouldnt keep my eye and apparently I'm intimidating! Who knew...

So yeah! Those are my results! Analyse as you will.
