Request: Your third cousin asks to bring her boyfriend-of-the-month
to your $150-a-plate wedding reception.

What you should say: “We’ve already had to make so many tough
decisions to get the guest list down to size. We really can’t
squeeze in/afford another guest. But I would love to have you two
over for drinks sometime so I can meet him.”

Why it works: If you illuminate some of your behind-the-scenes
planning, your cousin may get a clue about the inappropriateness of
the request.

Why you shouldn’t feel guilty: It’s your party and your pocketbook,
says author Patti Breitman.

How to avoid the situation in the future: Make a few calls before
you put together the guest list to see if there are new additions
you should consider as you plan.
