Freckles thumped at me! I’d thumped first, of course, but she responded. We were having a conversation -- a thumping conversation. Maybe she'd recognized my frustration and would humor me by stopping her digging.
The pause lasted for only a few seconds however, and soon I could hear the scratching sounds emerge from under the couch. I thumped my foot. There was silence, and then, yes, there it was again -- Freckles thumped back.
It became a competition, but it kept her from digging!
