I get home tonight, walk in to a very, very warm house (too warm) and SD13 in her winter coat, hat, and gloves. "Why are you dressed like that?" I ask. "It's very hot in here." She says, "I'm too lazy to dress different... yeah it's warm..."
I set my things down and check thermostat. It's 70 downstairs which means it's been on a long time and it was set higher. WTF! Damn, they figured out how to change it. I re-set it back to normal temp.
Taking a deep breath, as I'm certain that it's not going to go well, I talk with DH.
Me: the thermo was turned up over 70
DH: it's really warm in here! (Says this with pleasure)
Me: it's too warm! I recently re-set it warmer and someone's changed it.
DH...steps back with panic in his eyes and instantly focuses on my annoyance. Why are you so upset?
Me: come on! I re-set the thing for a reason. Do you want to buy a new locking thermo? Or maybe you pay more of what will certainly be a huge heating bill?
DH: why do you get so upset about these things?
Me: because I have no control! And why does it always come back to me?!
DH: that's not true!
Me: come on. I should have kept my mouth shut.
DH: maybe I'll just pay more.
Me: maybe you should set some RULES! (I also make the suggestion that certain people have the ability to put on sweaters and socks)
At this DH shuts down and leaves the room.
Nothing is said to SDs. I put note on thermo. I ordered a lock for thermo. I'll have that installed on Monday. Fixed.
