Far too long

A pretty nurse with short, frosted blonde hair and an eastern European or Russian accent ran down the stairs behind Rock as he tried to hurry out of the downtown medical clinic. It seemed to Rock he had sat in the waiting room far too long. He thought he had a cold, but it cleared up as he waited, and he had fallen asleep beside the nurse.
When Rock heard her shoes click on the marble steps as she descended toward him, he remembered he was supposed to pick up some medication.
"You have to get your medicine, sir," the nurse said.
Another nurse behind the countertop of a small pharmacy handed Rock his prescription, which was a plastic bag filled with pills and what looked like a three-dimensional puzzle of some sort, with shiny metal pins and white cubes about the size of Captain Crunch cereal bits.
"What am I supposed to do with this?" Rock asked his doctor.
"Just follow the instructions," he said.
