I've finally been "asked" this question by my grandmother this year - I have another cousin who is unmarried, and the two of us are the only grandchildren (of the first "group" of them) who are unmarried. I don't think my grandma talked to her about this, but she said to me "Maybe next year you'll bring someone to the family gathering for us to meet!"
I love my family dearly, but I don't think I'm ready to have anyone I would be seeing be subjected to the craziness that is our family!
