My mom made my favorite [lunch] because I think she knew how sad I would be with everyone gone. (4.10.3)
Charlie's mom also has her own way of showing affection. There's a lot of non-verbal, non-physical communication going on in this family. And if it works, it works.

Quote 69
I think it's sad because Susan doesn't look as happy. (1.2.2)
Charlie barely knows Susan, but her happiness, or lack of, affects Charlie emotionally. If Charlie is so empathic, why doesn't he ever do anything about it?
