Quiet Walking Woman Returns

She's baaaaaaack! Quiet Walking Woman had been off work for a week because she hurt her back (her cries of pain were silent, no doubt). I had not noticed her return until she shuffled up behind me like Charlie Chaplin and tapped me on the shoulder to enquire if the office kettle working. She really is bloody annoying. How am I supposed to know when to furiously Alt + Tab out of the Blogger window if I cannot detect her approach?
