What I learned today

When I was growing up, every night at dinner my parents would ask what we learned at school that day. I no longer live at home, regularly eat family dinner, or go to school, but tonight my answer would have to be that when choosing what to drink with your meal, "Ales are like red wine and lagers are like white wine." Yep, that's what I learned watching The Food Network tonight. But can it really be considered learning something if, intuitively, you kind of already knew it, it's just that you now have a more concise way of expressing it?
