Chris hugs Dahlia back happily. "Thank you. You're so nice, Dahlia."

She's given them more than material goods with this present -- acceptance, friendship, an offer of her time. Chris is happy to set up a date and time for their shopping trip, making sure Dahlia knows their address to meet up beforehand. (And if they plan on having some baked goods ready for her then, well... it'll be a surprise for the day of!)
