I am finding in the householding function way too many are getting listed as “Resident” because there are two or more with different last names. If you throw in a single step-child, in-law or live-in friend with a different last name, it gets captured as “Resident.” Addressing an envelope with “Resident” is a great way to have my mail thrown away. I would like to see the filter less sensitive, say 3 or more different last names, since 2 different last names could likely be the same family. New son-in-law that lives in the basement with your daughter won’t mind being lumped in under the household surname. But “Resident” offends them all.
