Lisa doesn't touch him even though she kind of wants too. Neither of them are huge on touch for different reasons, she knows his reasons but she's fairly certain he doesn't know she knows.

"Lenny...have you told him why? Or did you just say it wasn't his fault?" She asks gently, well as gently as she can. Her tone is soft but the word choice isn't the best. She learned some tact and subtly from her brother but with Mick and her father and the company he kept...she could be crass and straight to the point regardless of how invasive or hurtful it seemed.
