   Thanks for thinking of me for the panel. I'd like to pass on this one so I can keep my focus on my current projects.

   Thank you for the invitation to the Saturday team day. I won't be able to attend, as weekends are my time off. I'll catch up with everyone on Monday.

   A calm weekend boundary works here because it neither apologizes nor leans on an invented excuse.

   Because it turns down this plan and points to a later one, it fits someone you like and want to stay in touch with.

Examples

What to avoid

• Stiff, formal phrases like “regret to inform you” feel out of place for everyday invitations.
• Inventing an excuse you would have to keep up later is a trap, and a short, true reason or none at all is fine.
• A long apology or explanation invites the other person to negotiate.
• Saying “maybe” or “I'll try” when your answer is no only delays the disappointment.
• Leaving the invitation unanswered is harder on everyone than a prompt, polite no.
