"A music chatroom," Jason answered quickly and gaped across the table at Dan when he realized the man had answered at the same time. Though they had discussed pretending to be only friends around his mother, he didn't think it was necessary to lie about such a small detail. "I mean, Jae-Mi was part of the discussion, you know, uh, because of her playing in the symphonic orchestra in LA. He heard a recording of one of their performances and I pointed out she was one of the soloists. We talked a lot about music."
At least he managed to compose a lie composed of completely honest answers. He doubted it would work on his mother though.
