2) There is better ways to extend the conversation instead of inviting to my 'bedroom'.
3) No or other excuses means no, thanks and farewell.
4) conferences are professional places, no place for flirting (they invented bars for that).
5) Ring on the finger? SHE is NOT interested.
Somehow some men think that if the woman is NOT interested she has be 'wrong' or deserve more 'strong' signals. I support more woman at the conferences and I wish more woman take some stand at this cases and say it loud: 'TAKE OUT YOUR FILTHY HANDS from me' Saying that loud will teach a great lesson and avoid some posts. The main problem is not sexism is lack of politeness and manners.
