Dear Betty,

    I'm your eraser Jill. This afternoon you lost me in your classroom. Simon found me and gave me to your English teacher Ms. Green. Now Ms. Green's three keys and I are in Ms. Green's bag. The bag is yellow. It's on Ms. Green's desk. Please call Ms. Green at 718-0167 and ask her for me. You can come to the library, too. Ms. Green is in the library now.

Jill
