passing notes

Ami looks like a good girl, but she likes to pass notes in class, same as Usagi! She writes them in code to keep the messages safe.

Unfortunately, this note got lost in the bottom of her bag, and she can't remember how she coded it! All she can remember is that it was a letter shift. Ami wants to know what it says before throwing it away just in case a teacher finds it, but she doesn't have time to crack the code since she's studying for a test. Help!
