Today my daughter asked me to play Half Life 2 (she loves watching me play). So I told her that I didn't feel like playing anything at the moment. Then I quickly chimed with: "Hey, why don't you turn the computer on in your room and learn how to play it." She was like, OK! Cool! She did as such and I sat in and helped her navigate--only verbally. She worked out the mouse and w-a-s-d controls.
It was so cool watching her enjoy something I enjoy.
