When we first moved to TN, the exterminator asked me if hot water was supposed to be coming out of the front yard hose.
Then, we noticed that the master bath door’s hinged aspect was next to the light switch. *sigh*
You have my deepest sympathy for any household anomalies that make one do a face palm.
Here, the hot and cold water lines are reversed in the bathroom. Nothing I can do about that except remember it when I shower or use the sink.
