I've noticed that she's been really upset about something since about the beginning of the week, from overhearing her talk to people on the phone and I think she was crying once. It sounds like something happened to a member of her family and she's going home this weekend and I think monday (she was talking on the phone about cancelling her shifts) should I say something to her to see if she's okay? Or should I just let her keep it to herself (during the call she made today she went outside the room to finish talking) and not butt in?
