sad

I was chatting to a young shop assistant last week, young enough to be my daughter. We were discussing being alone at work, whether it was safe or not, and she mentioned a young guy had been hanging around a while, so she asked him if he wanted anything. He apparently blushed and mumbled something about just looking at her because she was so nice looking, and maybe mumble mumble flowers, mumble dinner? And she told him off, gave him some sort of rude dismissal, and called him a loser (to his face? not sure, but to me she definitely said 'what a loser' and totally slated him) I was, frankly, shocked and saddened. How much effort does it take for a shy guy to pluck up courage to approach the object of his dreams? To be so rebuffed must be quite devastating; is it any wonder guys feel they can't win? Apparently they are supposed to romance women, but NOT? What are the chances that guys who get knocked back like that develop into serial killers or rapists? OK I am being extreme, I realise that, but what happened to manners, or graciousness? Just accepting a compliment where given and saying 'thank you but I am not available', or maybe even 'you are kind but I can't fraternize with customers, thank you'.
Why did this affect me?
