What's the best way to handle a peer who communicates like this?
We are ready to have the piano moved. Thanks in advance for having it out of the lobby by this coming weekend.
Rather than having a conversation and asking if you can do something for them by a certain time, they thank you for doing it in advance and give you a deadline without even seeking to understand the reasons why you might not be able to accomplish what they want done, in said timeline? Reminder this is a peer from another department not a manager.
