Dear Sawyer,
We went to the aquarium yesterday and I gave you a snack and water bottle to put in your backpack. At one point, you left your backpack on a bench and when I picked up the backpack, it was heavy, like way more than just a snack-box-and-water-bottle heavy. I know you tend to squirrel things away in your bags, so I wasn't totally surprised, but I decided to see what else you were carrying around and when I unzipped your backpack, there was an actual ROCK inside. You'd found it the last time we went hiking and put it in your bag for safekeeping--and kept it there. I can't believe you walked around all morning with a heavy rock in your bag!
Love,
Mom
