When all else fails, try this.
Send the meeting invitation 3 weeks before the actual meeting. Make sure it's in bright pink.
Include a picture of a cute cat in the subject line.
When the recipient asks for clarification, respond with an email that's 3 pages long, but only says "I'm not doing it".
When they call you out, just say "I'm not arguing, I'm just explaining".
Repeat this process ad nauseam.
