Funny stuff. My mom's rotation was primarily comprised of Chicago, Eagles, Frankie Valli, and Commodores/Lionel. I have the better part of their respective catalogs committed to memory whether I want them to be or not.LOL I remember my mom playing this song every morning on the way to school. It's seared into my mind xD
My older brother is 10 years older than me. My older sister is 8. I think I was a "whoopsie" xDNah, just a guess based on what you said your mother listened to and various other factors. It's great to hear your in your late 20's. You still got a lot of living left to do!
