Citric Acid Juice

I was going to go to Make:Tokyo, but couldn't because my baby got fussy. He was so excited this weekend. It's almost an addiction of a hug. Of course, that's OK with me. But my spouse looks physically tired. So I bought her ume (japanese apricot) and perilla juice that is known to be citric acid rich.

As for me, I was finding time to implement a tiny Lisp interpreter for this weekend.
