Brrrrr Colder still

So far it has been 8 1/2 hours and still they aren't finished putting in the furnace! Apparently my house is arranged weird so the guy had to get 2 more guys here to brainstorm on what to do. Finally figured out where to put the pipes and they are working on that now. I am even colder now than I was earlier. It's around 58 degrees in here. Brrrrr. WHEN WILL THIS AGONY END?! I AM FREEZING! I'M ABOUT TO BECOME AN ICICLE!
