Yesterday afternoon, houseguest Butters found a sunbeam:

This morning, she found a corner of the couch:

Then this afternoon, after I took both her and Cassie on a let's-sniff-everything 15-minute walk around the block, I decided to take Cassie directly on a let's-get-real-exercise 25-minute walk. I could hear Butters protesting this action halfway down the block on our departure, and also halfway down the block on our return. My poor neighbors.
She hasn't left me alone all afternoon, either. She needs to know where her humans are at all times. Unfortunately for her, her real humans are about 2,800 km away and not coming back until Monday. I hope she copes.
