I shouldn't be hearing this

It's July 28th and I'm hearing a sound I never thought (or wanted) to hear on this date, the sound of the furnace kicking in.  The temps have been in the 50's for the last couple of days and it's getting ridiculous.  Hubs got home from Hawaii yesterday morning and after 10 days of the tropics, he couldn't handle the cold, so on went the furnace.  I don't approve of this weather.  You shouldn't have to dress warm to go out pea picking in the garden. I want a refund on my summer!!
