I "suggested" that Mrs Wbill engrave our anniversary date on the inside of our wedding ring. :-) That was a safe one.
Birthdays, I never have a problem with. Holidays, I do. They just get past me.... "Valentine's Day was last week?"
My husband had us marry on New Year’s Day so he could remember the date. Guess which one of us has forgotten the date. In my defense, it’s because I was working New Years Eve for the last few years and was just so tired.
