On Saturday morning, a neighbor approaches you at your mailbox and invites you in for a cup of coffee. Since the two of you have been friendly in the past, you have no problem with her invitation.
After exchanging pleasantries, your neighbor tells you that she wants to talk to you about something that's been bothering her lately. You can't imagine what the matter might be but you're all ears.
She tells you that since you've been neighbors for three years, she considers you a friend. After all, she watches your home when you're away and has walked your dog on occasion. She goes on to say that she notices that you entertain quite frequently and your parties seem fun but is somewhat disturbed that she has never been invited to participate as a guest.
You are stunned.
What do YOU do?
