They were traveling? Leaving Hogwarts during school. Greer had never been on a field trip before! She was rather excited. The couple that were offered at her muggle primary school she had been unable to go because of an illness. So this time she was excited, even if it was to the zoo full of magical creatures.

Looking at the form quick and pulling out her quill Greer gave it a quick John Hancock (American reference for those who don't know) ... she giggled a little at her own inside joke ... those around her probaly thought she was crazy. And handed it in. "There you are Professor"
