Meredith Goldstein of the Globe‘s “Love Letters” column has a wonderful question about a couple’s … sandwich incompatibility. You’ll want to read the comments (how often do I say that?), too.

In case any of you haven’t seen, in addition to today’s column, I have a feature on money etiquette in today’s magazine. This is an excerpt from Miss Conduct’s Mind Over Manners (which goes on sale Tuesday!).

Also, boston.com has a fun photo feature based on tips from MCMom–plus three bonus tips on Facebook etiquette.
