One of my aunts has 3 kids, ranging from 18 to 24ish. Her oldest and her youngest are both in relationships; I was planning on inviting them. I called my aunt to verify their addresses and she left me a voicemail saying that she didn't think her kids' significant others should be invited as it was a family event and they would have more fun alone. I really don't want to start any drama but I really don't agree with this. If they decide they'd rather attend alone, that's fine but I think they should have the option. I'm just not sure how to respond to my aunt without her thinking I'm disregarding her opinion and inviting them anyway. Any suggestions?
