I saw the cutest secret boxes in Maui, Hawaii. They look like wooden blocks on the outside but have a sliding compartment on the inside. I could slip Mark messages in here. After some research, I found the manufacturer and its retailers. There's one near my house.

I want to get him something his mom can't open if she finds it. That or if she does find it, something I can put coded messages in.

Mark means the world to me. I hope he likes it.
