Dear Queenie,
I have a neighbor who comes over whenever she sees I have company and wants to join in. She also comes over sometimes when I am busy doing something and wants to just sit down and visit.
Queenie, I don’t mind once in a while when I’m not busy, but this is just too much!—Harassed
Dear Harassed,
Your neighbour is apparently lonely, and either rude or just not very smart.
When you are not willing to visit with her, tell her you are too busy to visit with her just then and do not let her get past your door. If you are feeling – charitable? – give her a time when she can come back and visit with you.
