I'm reading a manga. Two sisters have just lost their father. Sister A laments that she doesn't know what to think, and sister B is just staring into the void. Then sister A says to sister B
Question: what on earth does she mean? In the dictionary, I find "dry", but that doesn't make much sense. Googling around, I've also found 明るい, but sister B doesn't look happy. My interpretation would be "You look like you don't care at all." or something like that, but that doesn't fit any dictionary entry I've seen.
