78! Holy Heaters batman, that is hot! How the hell do you sleep at 78? My roommate turned the heater on to 65 last night and I had to open the window and sneak out and turn it down to 62. If it were up to me, it would never be used.
Look, that pet peeve of over heating/cooling is mine too. I really think that has more to do with psycology than it actually being cold or hot.
Also, how the hell do you sleep in that temp? 78 is a good summer day, wearing a tshirt and shorts.
