I'm feeling worn out from sleep disturbances. Last night the cats behaved, but my husband's brother called at 5:00 am - - because he thought it was 5:00 pm. Not only disruptive but worrisome.

That definitely sounds unsettling!

That is very odd. Worrisome for several reasons.

How the hell did he get the time wrong by 12 hours?

Oh, that is odd.

Time-zone miscalculation? But yeah, it's a ...

Stereo Nacht : we're in the same time zone.

Indikon : My husband's parents were old when he was born, and his brother is 9 years older. He's suffering from cognitive decline as well as various health problems.

Swamp Daddy : he is in the stages of cognitive decline.

mimi : Yes. Made it hard to fall back to sleep.

Tamsie : That does seem like a good excuse. It’s unfortunate he has it.

That would explain it. Still disruptive and worrying though. My husband also had older parents and has a brother 9 years older than him. Luckily, still in good health.

Human's had similar things happen. Especially if waking up disoriented...
