Simply because they have an agenda.
My reasoning is that some folks weren't taught to communicate their feelings growing up and they are limited on how they respond to others, they seem to be uncomfortable expressing themselves on a personal level making them anti-social . They don't seem to be in touch with themselves and therefore seem very cold towards others.
can be because of hurt, lack of trust or just plain lack of compassion...
Maybe they were raised by cold hearted parents. Maybe they have been hurt or disappointed so many times they can no longer feel. I can't think that anyone wants to be this way.
There are multiple reasons and it depends on the scenario. Are the people they're cold hearted to STUPID?<br />
Because that makes sense to me.
Because life and people have destroyed them. Or because they have disturbed personalities.
