A calendar invitation can claim an hour before a conversation has earned it.

Booking time is easier than justifying it. A slot appears in someone’s week, the software marks them busy, and no one has yet established that an hour of several people is the right response to the question. Meetings often exist because inviting is frictionless while declining is awkward.

Before you send one, write the sentence explaining what has to be decided and who needs to be there. If you cannot, the answer is probably a message. And when an invitation arrives with no stated purpose, it is fair to ask what it is for before accepting.
