The difference wasn't only our ages, but the world we grew up in was very different too. I came up with the idea of being an only child with a brother and sister from the title of a book: My Brother Was an Only Child (Jack Douglas, 1959).
Beautiful page and interesting story! My husband, too, was in a similar situation to yours as he came along 14 years after his sisters. I'm glad you were able to re-connect with your siblings. I especially like your title work and the black and white elements to go with the photo.
