Now that my husband is retired, we have thermostat wars.  The thermostat is in the narrow hallway leading to the bathroom and bedrooms.  We are watchful when either of us is in that hallway.  He turns it up, so it went to 79 degrees yesterday.  I turned it down and frost formed on the inside of the windows.  If I am in the bathroom I can hear his feet go down the hall and I know that he has adjusted the temperature.  I just turn it down when I come back to the living room.

Up, down, up, down…all day, all night.  We do not say anything.  We have this game going.  He falls asleep before I do, so I get the last adjustment of the temperature.
