Sometimes during the conversation the girl starts to play with her mobile, writes SMS etc. I am always impressed with this high level of impoliteness, that I would never be able to do, even if I would force myself to do it. But for girls it seems to be normal to write an SMS during a conversation. Of course it's some kind of rejection, but still I don't really know how to deal with it. Yesterday I asked a girl if she has time, she said 'Yes, sure.' We spoke for about 20 seconds until she puts her mobile out of the pocket and starts to write a message. What should I do? Just go 'Thank you for your time, I have to go now.'? Or even say how impolite she is (in a playful way)? Just ignore it and proceed with the conversation?
