My engagement ring is missing again . I can remember lying on my bed with my head towards the fan and the ring on my finger and I was trading from finger to finger , from engaged hand to married hand . I can not remember though whether that was when I fell asleep last night , or when I napped early this morning , or when I caught ten winks this afternoon , or whether tonight . I ' ve been napping a lot lately .

Question: Why does the narrator feel panicked ?
They ca n't find their engagement ring .
