My birthday is today (30th) and I have a friend here who's birthday is tomorrow.
One of my best friends was on Jan 1, but he left us last year. His birthday was literally two days after mine. (He was exactly that much younger.) He used to phone me and call me an old fart on my birthday.
Anyhoo, happy birthday to all of us who were deprived of the coolest gifts when we were kids because our birthdays were so close to Christmas. At least everyone is in a party mood around our birthday time.
