"I will," Jen answered automatically, though she probably wouldn't ever ask Rob for anything, except as a last resort. It was more than sweet of him to try to help, but at the same time, he was only in this situation, and only offering, because of Jeremy. And even if he didn't see it that way, she didn't want to use him.
She bit the inside of her cheek to hide a smile as Milton's eyes lit up when he saw the baseball cards. He might not completely understand sports yet, but he loved playing with cards, especially 'fun' looking cards; she assumed he'd inherited it from Jeremy. "What do you say?" she prompted, when Milton took the packet and, unsuccessfully, attempted to rip it open.
"Thank you," he said, his response only slightly less automatic than Jen's had been, preoccupied with the packaging. Giving up, he held it up, back to Rob. "Open it? Please," he added as an afterthought.
