Science is my specialty, but... I've always enjoyed language, both native and foreign. It's a wonderful gateway into all sorts of topics, like history, geography and cultural studies. Given the mixed heritage of our family, it's very relevant to Deimos' life. I hope he enjoys it, too.
... as for cooking, I like to make lunches for Shiox and Deimos. I like making and packing bits of their favorite things. And with baking... it really depends what is in season. I like to include fruit whenever possible.
