I absolutely hate this trend of young people calling adults by their first name. I always use a title when speaking to or referring to anyone older than myself. That's what my folks taught me, and I do it to this day. I have a dozen nieces & nephews, and very rarely does one call me "Aunt". I, on the other hand, would never dream of calling my aunts & uncles by their first name. My teenage daughter usually uses an adult's first name, even tho' I've told her (repeatedly) that I don't think it's polite. There are some adults that she addresses with a title, tho. I'm not really sure how she's decided to differentiate between the two groups
