In a comment to a post below, Patti Abbott says that there are some "kid's books that stay with you a lifetime." She's talking about ones she's read as an adult, but the ones you read when you're young stick with you forever, too.
A little over three years ago I did a post about the first book I remember every having checked out of the public library in Mexia, Texas. I mentioned that I'd been looking for the book ever since without success. The reason it had proved to be so elusive was that I had the name wrong. I thought the book was about a flying pig named Clementine. A few weeks ago I got an e-mail from someone who'd just read that post (God knows why) and how informed me that the pig's name wasn't Clementine. It was Clementina. So I immediately looked for the book on-line and found it. If you've clicked the link, you'll notice that I must not be the only one who liked that book. Judging from the price, it must be a highly sought-after item. But I'm glad to know that it exists. I was afraid that I'd just made up the whole thing.
