DEAR MISS MANNERS: I have been married to my husband for 35 years, and his siblings treat our home with no respect. Yet when the in-laws arrive, they treat our home as if we lived in a dump. Why would they treat our home with no respect -- or more importantly, treat us with no respect? I guess my question is twofold: Why the lack of respect, and why won’t my husband speak up? Miss Manners would think you would make that easier by covering your tables with trays or coasters and using old bedspreads.
