+1So, although I don't believe I'm a cold,heartless bitch. A lot of people seem to think so.
People I'm close to don't perceive me as cold (or so they say) but most everyone else, yeah, pretty much.
I haven't really given much thought to what it means. Can't say I've ever thought of someone being cold as a bad thing (unlike "heartless bitch", which is less.. equivocal). It's not synonymous with cruelty. It's about energy. How much emotional energy one emits. Some people have superior insulation.
Funny that warmth is universally regarded as a positive trait. Sometimes, overly warm people make me uncomfortable. As in "I think I'll just step outside for a bit...".
