Yes, I would be sad but I would also give my friend a break and let it go. Yes, it could be she just spaced it, did not put it on her new calendar, or who knows.
I do have a good friends whose birthday seems to always be the first day of school. I am the type who has always remembered friends' birthdays...dont usually even need them written on my calendar, I just remember. However,I have forgotten it was her birthday for the past 2 years in a row...and remembered a few weeks later. The first day of school has been so stressful here. I am so glad that when I call my friend to apologize, she has always been gracious and light-hearted about it.
