Dad, I just realized it’s been Charlie the whole time!! Remember when I couldn’t find the bird in the gas station parking lot that sounded like lasers? That was Charlie! And when I couldn’t find the chirping that sounded like a bird that burned its little wing? That was Charlie, too! Maybe you already knew that Charlie was an amazing whistler, but I had no idea. I bet that’s what y’all were doing in the mornings on the back deck when I slept in so many days last summer. I really can’t believe that Charlie has a talent that I didn’t know about. Wow…
