Oliver was actually relatively surprised at how easy it was to find a book on the shelf that would interest his Mother. There were several and he took several moments to decide. He was tempted to just buy the entire shelf to save him the hassle of choosing, but figured his Mother would never read all of them. Instead, he simply reached out and pick two random ones. Yes. Combine these with the flowers and card and he had the perfect gift.
When Sabrina returned, Oliver glanced up with a grin. "Good," he responded, lifting the two books he'd chosen. "I found some easy enough." Now that he knew what he was going to do, the slight panic that had set in during his previous hopelessness had receded and he could breath a sigh of relief.
"Thanks again," he grinned, "You're a life saver."
