You know, when everything comes together at the same time to cause the maximum difficulty.
First he had the MRI scan, which I know is worrying him.
Then the sprained ligaments that meant not only could he not go to work, he was stuck in bed with his foot raised.
He had his new hearing aids fitted and it always takes him ages to adjust to them.
It was completion time for the boat sale, so lots of paperwork/phone calls to be made to organise the re naming, license, boat safety certificate etc. etc.
All the reasons above are why I didn't throttle him when he was being a major pain in the arse!
