Many happy returns, Franbern, enjoy your celebrations! 🥂 🎂 🎈
I've always kept cards up for two weeks, and I also keep the ones from the grandchildren. If we went on holiday for my birthday, I took my cards with me and displayed them in the apartment!
I've also kept my birthday, Christmas and anniversary cards from late DH, so when I celebrated my 70th last year, my first birthday without him since I was in High school, 😥, I had a nice ' Wife' card to put on display along with Mum, Gran, Sister, Auntie. It felt right to me, I did the same at Christmas and Valentine's ( our Anniversary).
You'll probably think I'm daft! 🥰
