"This is going to be amazing!" I declared, clapping my hands together. My brother, Ethan, rolled his eyes, but I knew he was just as excited as I was. We stood in front of a heavy oak door, the only entry point to my grandfather's workshop.

I grabbed the key and swung the door open, the scent of sawdust and varnish hit me like a wall. Light streamed into the room, illuminating rows of tools and half-finished projects. I immediately wanted to pick up all the tools.

A set of intricately carved wooden animals sat on a shelf. A smile stretched across my face. I knew exactly what I was going to do. Ethan, to his credit, was already reaching for the woodworking bench.
