All the time! I love reading my childhood favorites and remember how I felt when I read them. I found a book as an adult that I asked my mom for when I was in elementary school--it was in the school library--but it was out of print, so she couldn't get it. When I re-read it I recalled how much I loved it, and the smell of the school, and even what the library looked like, and also that the book is what prompted my interest in dog obedience trials.
