Dear Abby: Did my husband really snub my sister or is it in her head?

Dear Abby: My sister recently traveled across the country to visit my husband and me. We had a pleasant time together, but at our dinner party on her last night, she decided that my husband was not merely snubbing her but had instructed other guests to snub her as well — to ignore her conversation and look away when she spoke. Abby, nothing like this happened!
