I think that a better question would be how do we actaully connect with emotions.
As for myself. Well this is my natural state so I don't feel a need to sympatize with people. I help them if I can but I tend not to use emotions in such a situations.
Actually the more emotional you are the bigger are chances that I will not be.
Of course this got me into alot of trouble over the years but I can't help myself. For example I can be in a room full of depressed people without turning into one of them.
I can also sit at a table with 10 people for 4 hours and not saying a single word all this time. What is not because I can't say anything. But because I am not interested in discussion because of emotional exchange. Basicly it all comes down to how you look at people.
