Is it 2010 already?

I haven't heard a lot of talk about resolutions, yet. Now, at 2010, we are firmly entrenched into the new century/millennium. I did hear someone say that we are now ten years into the millennium. Of course, that brought up the subject of when the calender actually start. To make it simple and to "cut to the chase"; I asked him when he counts to ten does he start with zero and end at nine or does he start with one and count to ten. Eleven is actually the beginning of the next group of numbers, not ten. 2001 began the millennium, not 2000. Also, being at work and in charge of maintenance, I get to hear about how hot/cold and damp/humid it is in here. Which gives me the opportunity to introduce into the conversation the actuality of the non-existence of cold. Cold is a relative term and isn't a quantity that exists Per Se. Actually we measure heat in greater or lesser degrees. There is a sun that produces heat but no ginormous ball of snow producing "cold". There is just heat and the absence there of. Once you remove all heat it cannot get colder. Placing ice in a drink uses heat energy to melt the ice to make it, um, less hot. As you can imagine, this discourse usually has the desired effect of boring whomever is hoping for more heat/cold; maybe even introduces the idea that such things are relative.
