they say it's a polar vortex. i don't know 'xactly what that is , but it's very, very cold. thursday night our furnace stopped workin' and my Mom was very worried 'bout that. it's so much money for a new one, and with this awful cold if they couldn't get it workin' right away what would we do? we were lucky tho. they were able to fix it for "only" $670 and we have heat. whew. my Mom said we dodged a bullet. i don't know what that means. i'm just glad the house is warm. right now is 7 degrees outside and they say with the wind chill it's -15. my Mom took sunflower seeds outside for the squirells and birds and nobody even showed up to eat. too cold.
