Arya's smile had a lot of teeth and suggested that she really didn't want to actually give him the real answer but... well, she hated lying to Armaan. It always made her feel gross.
So she took a swig of her drink and- well, first she paused and made a face while bubbles went up her nose a little, but then she gave Armaan that same smile again and said, quietly, "he's 46." Then, before Armaan could say anything, Arya pushed forward: "But he's sweet, Armaan! He's so good to me and we work so well together and he likes robotics and we're gonna move into together as soon as he-" Uh, oop, no, not that bit! "Well, we're gonna live together properly, soon."
