We saw a banner featuring robotics research on the local university campus during a family walk. This caught the eye of DS2.5, who is a robotics enthusiast.

DS: "Mummy, can I learn to build a robot like that one [on the banner]?"

Me: "If you go to [university x], you can study to specialize in robotics. But, knowing how Mummy and Daddy operate, we'll probably teach you when you're much younger if you want."

DS replied, "I'm much younger now! Can you teach me tonight?"

So we agreed to get started.
