L tries really hard to not allow any disturbances in session. She tries to remember to shut off her phone. If it does go off, it's usually a reminder alarm. I think one time she left it on for an emergency. I remember one time someone came and knocked at the office. I think it was a colleague. It was the first time I have ever seen her mad. We were sitting in the lobby once at night and someone came in. She got really mad at that too.
