The vindictive spirit tells me to say, "We aren't used to being around people like you." BUT! The real person in me says to invite them. Who knows, they might decline and just send a card instead.
My mom and aunt and I are really offended, my mom's cousin's daughter is getting married in Maryland, and my mom and dad and my aunt were invited....BUT NOT MY GRANDFATHER!
Granted he wouldn't have gone anyways just because he's getting up there in years, but it is still really upsetting that they didn't even bother to send him an announcement. But my grandfather is the kind of person that will send a card and a little gift no matter what...a better person than I.
