Andrea's theory of relativity

Einstein may have understood the physics of time and space, but I don't think he ever mentioned the relative temperature phenomenon.

Today Milwaukee temperatures were in the low 20s. It felt downright balmy. People were walking around with untied scarves, open coats and only the elderly were still wearing hats. we still have a good layer of snow and ice, and yet street shoes are back - winter boots are back in the basement where they belong. And tomorrow we're supposed to see mid-20s. No doubt we'll see people headed to the beach.

20 degrees is not warm by a long shot. But after weeks of single-digit highs and below-zero wind chils, it may as well be summer. Conversely, when it's 90 degrees in the summer, a dip down to 60 sends people inside for hot soup faster than you can say split pea.

I have no supporting equations or scientific research to show for Andrea's Theory of Relative Temperature, but I'm sure it's true.
