The Erasure of Jacob's Birthday

I was asking Jacob what he wanted to do for his birthday and he told me that he wanted to have an "all boy", to include Steve, Spencer, Seth and 3 other boys from school. I told him that I could not guarantee that Spencer and Seth would be able to be there. To which he replied, "Then just erase my birthday." That is some serious business. Completely erase your birthday? That is some major cousin love. I do love that those boys are best friends.
