DEAR ABBY: Does being invited to an engagement party "guarantee" you
will also be invited to the wedding? -- LOOKING AHEAD IN WASHINGTON,
D.C.
DEAR LOOKING AHEAD: Yes, it does. And for that not to happen is a huge breach of etiquette on the part of whoever is hosting the wedding, whether it's the bride's parents or the couple themselves.
Just in case you didn't know and can't read between the lines - this also goes for anyone invited to your shower/bachelorette/stag/bachelor/etc party.
