Up Against the Wall

Exploring my neighborhood listings on Unilocal I came across Up Against the Wall — listed as an art gallery. Seeing someone working on frames and such inside while passing by, I decided to inquire about any upcoming shows. The occupant was reluctant to come to the door. Here’s a rough approximation of our encounter. All shouted through a mail slot, mind you:
Lady: Yes? I’d open the door, but I can’t find the keys.
Tara: Hi! Are you open?
Lady: We’re never open. How did you find out about me?
Tara: Online. A website called Unilocal.
Lady: That’s unlikely. I don’t advertise.
Tara: So, you don’t have shows?
Lady: Nope.
Tara: So, you aren’t open to the public?
Lady: Nope.
Tara: Well, okay. Thanks anyway.
I’m not sure what goes on there, but we’re not invited.
