Dear Headmaster Dumbledore Sir,

Dobby is in a bit of trouble, sir. Dobby was walking when Peeves flew out and well, to make a long story short Dobby is stuck in a suit of armor. It is really dark and there's a spider and Dobby doesn't like the dark OR spiders. Dobby would like some help, sir! Please! Dobby is sorry for breaking that vase in the library, sir!

-Dobby

P.S. Dobby is not good at using pronouns.

Dear Mr. Filch,

If you walk by a suit of armor that is making noise, please remove the house elf from it. Also, please repair the vase in the library.

-Dumbledore
