My best friend growing up was born on her grandpa's birthday which was very ironic to me because she had 1/365 chance to be born on that day. Thus I came to the conclusion she was adopted as a birthday present for her grandpa and I managed to convice her of the same. A few years later I discovered that my due date was on my grandpa's birthday, but I happened to be two days late. I was quite embarassed of my mistake.
