Nasim couldn't find Taylor at the motocross show. By the time he got home, it was too late to put the purse in the mail. Early the next morning, he tasked his mom with mailing the purse back to Taylor ASAP.
During the night, though, he'd had a chance to make a little addition to it. He wrote the letter to Taylor just before he went to bed. In Nasim's own words, he just wanted to make her smile when she read it.
