" He’s talking intently on his mobile phone and sipping a cup of coffee and frowning at something in the paper. But then he looks up and his dark eyes meet mine, and his whole face breaks into a smile. A true, affectionate smile, which makes him seem like a different person.
When I first knew Luke, I only ever saw him businesslike and polite, or scarily angry, or—very occasionally—amused. Even after we started seeing each other, it was a long time before he really let his guard down. In fact, the first time he really, really laughed, I was so surprised, I snorted lemonade through my nose. Even now, whenever I see his face creasing into a real smile, I feel a bit of a lift inside. Because I know he’s not like that with everyone. He’s smiling like that because it’s me. For me." (Shopaholic Takes Manhattan by Sophie Kinsella) "
