AD: Examine notes.

You recognize both of these notes. You wrote and delivered them to your neighbor to get his goat.

One of them has something on the back. He wrote a rebuttal on the other side and taped it to the back of his fake safe for your viewing pleasure.

Luckily, the combination to your safe is on this paper. You carelessly composed your note on this document without noticing.

> AD: Use it to open safe.
