Who Writes the Wedding Thank You Notes?

I have yet to receive a wedding thank you note in the groom’s handwriting (to be extremely fair I have received very few wedding thank you notes to make a complete¬†analysis), but Jaya assures me that her husband wrote exactly half of their thank you notes. So it got us wondering how other couples had broken up the thank you note duties. Was your division fair? Did you swap families (I think this is cute because it gives your families a good impression of your new spouse)? Vote in our poll and then give us details in the comments.
