Have you ever moved into a place and found objects left by the previous occupants?
Here are several I found in the Kerouac House:

The snow globe would have been nice, except the water was discolored and I couldn't successfully replace it. Instead of a magical urban wonderland, it conveyed an impression of pollution.
The hair sticks are pretty and I would have used them, but my hair has been far too short during my time here. I'll leave them for the next resident where I found them, in the pencil holder over the desk.
In case you think it's okay to use a stranger's toenail clippers, I will now do you the favor of informing you it is not. Better yet, I'll put my gloves back on and dispose of them as a safety measure.
Beneficial objects in the house far outnumber the likes of the toenail clippers, of course. This is all at the front of my mind as I'm packing today. I promise I will try to leave behind only good things, like chocolate biscotti and blank CDs. If the next resident finds a hair in the drain or an inauspicious fortune cookie at the bottom of the kitchen drawer, I'll hope it wasn't mine.
PS - The reading was so fun--my thanks to the kind and lively crowd that came.
