"I just thought I'd say hello."

He considers how to address his status since he wants to say that he's new here, but apparently, he's not. Apparently, he lives here in a house, working at an animal shelter. But he doesn't remember any of that.

He considers just being honest, realizes it might be awkward, then reconsiders since it sure seems like a lot of people have the same problem as he does. Which has made him a little suspicious, truth be told. Which changes his mind.

"I don't remember anything about this place, so I thought I'd walk around and see if it helped. I just got out of the hospital."
