answer:Two come to mind for me. Firstly, my 4th b-day. We had just moved into a new home which turned out to be the home my family would remain in throughout my childhood and well into my adulthood. As I was the new kid on the block, we invited pretty much everybody in the neighborhood close to the same age. I made some great and very long lasting friendships there. Secondly, My “second annual 39th b-day”. On my 40th b-day we had a big party and jokingly called it my second annual 39th b-day. It was such a success that the tradition has stuck and we now have an annual 39th b-day party every summer.
