I am 28 years old, but because I'm going to grad school, I am living with my parents. I was invited to a family wedding on my parents invitation as "Mr. & Mrs. Jones and daughter". I felt very slighted by this invitation (my younger sister, who lives by herself, received her own invitation 'with guest'). I would normally give a generous check as a wedding gift, but I'm not really feeling that generous since they couldn't even figure out my name to put on the invitation. What is the appropriate thing to do? My cousin is the groom, and we see them several times a year. I've only met the bride a few times, so I don't feel comfortable confronting her about how the invite was written.
Yes, you should have received your own invitation. However, this is just a slight etiquette breach. It really isn't something to be upset about. And, unless you are in a relationship, they are not obligated to offer you an escort. So, to confront someone over this would be improper and impolite.
Money isn't the only gift and some find it a negative. So, give the gift you can afford and want to give. If you don't attend, you don't have to give a gift.
