Some anniversaries are important: wedding, birthday... to us. For men in general, they could not care less...
My parents have been married 39 years... my mother always nicely reminds Dad of important anniversaries ahead of time... and he does not remember most of our birthdays...
So far no major problem... and they've survived loss, cancer and accidents together (and put 6 kids through college).
We all need to learn to pick our battles...
