Emily won a stuffed gorilla at a fair when Maddy was much younger, and the gorilla and Maddy are best friends and lovers. Maddy loves to hump the gorilla. It’s basically a daily activity. When asked, the vet explained with a grin that there isn’t any harm to it. Keeps her energy up.
It’s quite the party trick, though, and usually occurs under the dining room table. Based on my previous descriptions you can imagine what this sounds like. Suddenly Maddy will start up with the gorilla. I won’t suppose about whether or not she enjoys people watching, but it is very clear that she doesn’t mind.
It’s one of the many things I’d ask her about if she ever did start to talk. I’d try to do it tactfully, of course.
Alas, she hasn’t started speaking. Yet.
