I think a "make it right" activity is in order. She'll then be over the moon that I remembered, albeit belatedly, and I can pretend I never forgot! In fact, she constantly gets the actual anniversary date of 24/1 mixed up with Australia Day 26/1 as it was the weekend prior to Australia Day when we were married. The certificate says 24/1 but in her mind it the mental trigger is 26/1 so its tomorrow right?
That's why we always forget ours too. I'd planned to get married on 14th March which also marked the anniversary of settlement for my first property. The reception place was booked so we brought it forward a week. So I always remember on about the 10th of March that we forgot it. To make things worse my SIL got married a week after us so I always remember her anniversary.
Your plan sounds good Michael.
