Guide to Addressing Envelopes with a fun twist. If you are like me, this time of year, I'm trying the remember the proper way to address envelopes since writing "Mom & Dad" simply doesn't work for the post office. This weekend, while addressing envelopes, I put together a list of the ones I used plus a few more. Instead of using the usual "John Doe and Mary Smith" generic names (sorry John & Mary), it was a lot of fun picking out these special names. We used the names of passengers from the Mayflower.
