Becoming Concerned

So I've got this big project I have to do for my Foundations of Marriage and Family class. We have to interveiw several relatives spanning at least 3 generations, and write a 10 page paper on our "Family Folklore". Naturally I decided to use my father's side of the family, because they are a little unique. So I contacted several members of my family almost immediately after first learning of the assignment. I spoke to my grandparents, three aunts, two cousins, and my parents. All of them acted as though they'd be more than happy to help me out. So far, only my grandparents have actually sent me any information. Luckily, they've sent me a lot. I lvoe my grandparents, they are great. The others however, have yet to get back to me, or have gotten back to me, and changed their minds about helping. How nice. Of course, my parents are still going help me, but my aunts and my cousins seem to have changed their minds. Great.
