BF and I are exact opposites....he works construction all day and comes home cold.....cranks the heat! I am frugal by nature and usually leave it set at 68......although here in MN the wind chill does factor in, but we have a fireplace that helps. We buy lots of flannel pants, sheets and fuzzy socks to get us thru!!!
Besides, when it is a little chilly in the house he likes to snuggle!
