My DH was a ‘monkey’ with his diary when he first retired. I’d always displayed my life on the calendar on the back of the kitchen door, but he kept his stuff to himself in his beloved Filofax. Eventually, he had an event, that made life difficult for me, so he agreed to sit down every few months, so I could put his on-goings on my calendar. Just letters, F for fishing, T for trial, J for judging, KC for monthly meetings in London, etc. but it was more than enough to keep things organised.
He hated holidays and thought them a waste of money, but had no problem with me going off with the DDs or friends, as long as we agreed on dates. You could say he was selfish, but he’d worked away for years, earned good money for us to enjoy life and retired at 55 to spend his retirement as he’d always planned. Sadly diagnosed with lymphoma at 65 and died Judy after his 70th birthday.
