Several of these individuals - we're not cohesive enough to be called a group - like to remember and recognize each others' birthdays. And because my kids and I couldn't manage to get together on the actual day, we agreed on 10:00 AM on Saturday. That worked out well, since it put my family group and my friends in the same place at the same time, and for some, for the same purpose.
My dear friends put a lot of thought into the gifts they brought me. Not expensive gifts, not the generic oh-this-will-work-for-anyone gifts. They know me, they know what I like, they know what I need. I love them all.
I feel a little sad for people who think they are too grown-up to celebrate their birthdays.
