The copies of the Hobbit and LOTR that my parents gave me over 20 years ago... and which were their copies before hand. I have read them into the ground.
I do know how to ride a bike. I have a distinct memory of going down a hill without my parents holding the back of it and falling into a fence. Didn't get too banged up and it was an awesome lesson to learn. Of course, haven't ridden a bike much in recent years, so who knows how proficient I am at it!
I like second chance stories when they are done well. I recently finished reading _Black Hills_ by Nora Roberts, which is a second chance story. And of course, the lovely Jane Austen has a number, which is part of the reason she's my favorite author. GUARDIAN sounds quite interesting and I"m looking forward to reading it.
