Ms. Thornbee

"A" is for the apple that he gave to me
But I found a worm inside
"B" is for beloved that I called to him
Before he left my side
And "C," see what he did, that's "D"
Did it to poor old me

Poor Ms. Thornbee. Her partner left her without warning one day and hasn't responded to any of her letters since then. She hasn't been the same and is often seen lamenting to her students and generally to anyone who listens. She still keeps the apple she got from her partner and the worm that came from it, the two having bonded over the incident. The townsfolk care for Thornbee a lot, so they've been on the search in her stead!
