Today is my birthday, so here’s a birthday-related anecdote for you.
About a dozen years ago, I went to a lecture at a nearby school. As we waited for the lecture to start, the lady in the seat to my left started talking with me. After a little while, she mentioned her birthday is August 11th. The lady in the seat to my right overheard, and she told us that HER birthday is also August 11th. At that point, I revealed that my own birthday is August 11th, too!
None of us had ever met or even seen each other before, but we’d all just happened to sit side by side by side! Since then, the lady on my left has become a good friend, and every year we celebrate our birthdays together.
