Hi Tango2x2/Keh!! I had no idea it was you!!

Thanks for mentioning it, I'll try to fix my pic as soon as possible

Yes you're right, the other party won't and shouldn't say "no" without giving a reason. Personally I can "take" it better if they do it with some style though, it's like wrapping up a horrible gift in nice wrappingpaper. It makes up for it, in some way 
When I don't want to dance with someone, I try to avoid the person as much as possible! By like walking to the ladies' room when a song is over, or by dragging one of my friends on the floor.
I'm always in for a dance though, with anyone, so it doesn't happen that often
