〔R7〕   What is it that, after we have fastened, bolted, locked, barred the house, placed a watchman on guard, and taken the keys with us, yet before morning, goes out in spite of us?

〔譯註〕 它是什麼？它在我們關緊、閂上、鎖住、擋了家門，放看門人守衛著，而且身邊帶了鑰匙以後，可是在清晨之前，它卻不管我們地 “goes out”.

                  註： “goes out” 可指「跑出去」，也可指「熄滅」( = extinguishes)

〔提問〕 If it is something in the grate (爐格子、壁爐), what is it then?
