The Narrow Road to the Deep North:

Finally, I sold my house, moving to the cottage of Sampū for a temporary stay. Upon the threshold of my old home, however, I wrote a linked verse of eight pieces and hung it on a wooden pillar. The starting piece was:

Behind this door
Now buried in deep grass,
A different generation will celebrate
The Festival of Dolls.

What did the next homeowner do with the paper containing a handwritten verse of Bashō?
