Big Z is officially fired from her job as big sister. Earlier she noticed that there are sprinklers in our apartment and asked me what they were for. After I explained it, she went about her business. Last night, Little Z asked her sister what they were. Instead of saying they are sprinklers and they put out fire if one is in the house, she said: That's the thing that spits out fire. Guess who can't sleep now, and is afraid her room is going to burn down in the middle of the night?!
