"Whoa!" When the knife hit the target, Devika clapped and cheered. "Roxy, that's amazing! And you did it so casually! How long have you been doing that?" She couldn't believe her new roommate was a knife thrower. It was almost like a circus act. "I'd be honored for you to teach me." 

The app was helpful, but she definitely realized that Roxy was not a cook. That was fine by her - Devika liked to cook just fine. It would be good to have someone besides her to cook for. "Any preferences for things you like to eat, Roxy? I think... if it's alright with you, I'll do most of the cooking." Hopefully Roxy wouldn't be offended by that.
