INT. MARY’S HOUSE - VARIOUS ROOMSIn my addled brain, I got this image of Mary chasing after the dog while trying to put eyedrops in her own eyes. Do one thing at the time, I thought, don't cripple yourself by multi-tasking! Then I realised she was probably trying to put the drops in the dog's eyes.
MONTAGE as Mary chases after the dog, trying to put in the eyedrops. Every time she has him cornered, he manages to escape, ducking under the coffee table or vaulting over the bed.
Like I said, a bear of very little brain.
