Chris chuckled at Ernie's comment but at the second point his eyebrows raised just a bit before he controlled his features and smiled lightly. "Perhaps I could learn a few things from you when it comes to pick up lines, and I'm always up for dinner with a friend." He put just the smallest emphasis on the word, wanting to make sure the younger wizard was heading in the wrong direction with this particular invitation.
Chris was flattered, to be honest, but 'as straight as an arrow', as his Uncle might say, and he didn't want to embarrass Ernie at all if there was any inclination behind the dinner invite.
