Most of my company works remote, and with C-19 we are now all working remotely.
One of my coworker runs many meetings via phone/video. He always ends them the same way: He says , “Good work, everyone! Talk with you soon.” then takes a moment to play with his dog before his next thing.
This has trained the dog to expect to be played with at the end of any phone call but only if he says that key phrase.
In fact, as kind of a “party trick” he showed us that now if he is at his computer, he can just say “Good work, everyone! Talk with you soon.” and his dog will run across the house and jumped up onto him expecting to be played.
