Will it happen again?

I'm really curious to see if Jean forgets my birthday for the 3rd year in a row. I almost hope she does so this anger can be fueled even more. I've continued to send her cards for her birthday, her anniversary and a birthday card to her husband for his birthday. Plus Christmas cards every year. I've tried to forget these events but it's impossible. She's had the same birthday for 52 years.....so have I. How can this surprise her every year? It's not like I randomly change it. We'll see what happens.....
