When you wake up because something feels odd... I went in to the living room door wasn't locked go over to my thermostat and the damn heater is on.... Check out side and my new puppy was left outside on the porch he will so scared I am so angry with our roommate my husband will be hearing about this. Second night in a row he's pulled something and I'm getting sick of waking up to being overheated and have a mind crushing migraine
