Women 📖.
I've had three partners in my life.
The first started off nicely, was easy to live with "most of the time" but showed her true colours in the divorce.
The second started of very nicely, but in a very short time things changed when I realised I was "never right", "I don't like that!" etc, she was the queen of mood swings (bordering on unhinged) so I quit while I was still alive.
The last (and current) is intelligent, agreeable, personable and shares my interests even though they're not really her thing.
When I bought a new car (VW Golf R) without telling her anything about it, her comment when she arrived home and saw it was "that's nice, I like the colour, and the headlights look cool!".
I buy a new motor cycle and she usually likes the colour and never asks how much I paid for it.
However...............I have never sold a watch (well, not yet) so only time will tell.
