Kadiera's Playground Cute but Evil - it averages out

Barry's already heard this gripe this morning, so feel free to skip this one, hon ;)

When addressing envelopes using formal etiquette, the address should never be:

Mr & Mrs John Doe and family

or, by extension,

Mr & Mrs John Doe and son

Children have names. Their names should be included on envelopes. Formally, that'd be:

Mr & Mrs John Doe
Master Jeremy Doe, Miss Jennifer Doe

(assuming that Jeremy is under 13 but older than Jennifer)

If you're addressing the envelope more informally, you use:

John & Jane Doe and Jeremy & Jennifer

This has been today's grammar PSA. Thanks. :)
