Miss Manners: Just write the darn thank

Dear Miss Manners: What do you do when the duty to write thank-you notes overwhelms any genuine sense of gratitude?

In my own upbringing, reciprocity and eagerness to give were prized over the finer points of expressing gratitude, and I confess that my gratitude muscle has suffered as a result. I am trying to strengthen it by practicing writing thank-you cards, starting with large events, such as my wedding and baby shower.
