I have twin aunts who are only four years older than me. When I was a kid they would sometimes babysit me, in concert or, more often, singly, but always with their respective complement of friends. I vividly remember one time when one of these aunts and all of her friends asked the 7 year old me what my favorite group was. Well, I responded with the only "group" I'd ever heard of (the Partridge Family.) They scoffed and teased me about it, and when a Partridge Family song came on the radio they would stand at attention and observe it with mock solemnity in my honor. She used to give me the albums as gifts sometimes. I guess I never lost the taste.
(They also used to say continually "hey babe take a walk on the wild side" and when I first heard the song years later it was a pretty big "click".)
