On Oct 20 Zach and I were making Christmas cards together from scratch using recycled Christmas cards from previous years. Zach picked up one I made years ago with the words "Peace on Earth," on it and announced that this was a good birthday care for Jackson. I pointed out that that particular phrase applies to Christmas, not to a regular birthday, and Zach promptly responded by saying that since Jackson was born on April 22, which is Earth Day, it applies as much to his birthday as to Christmas. Although he thought of it first, I immediately recognized the accuracy of his insight and complimented him for it.
