Sophie Vs. The Eye Doctor

Sophie had an eye doctor appointment this past weekend.  Apparently giving eye exams to younger children can be difficult and they wanted to make sure that everything would be alright.  So they called in advance with some questions.

"Is your child able to recognize her letters?"   - Not a problem here.
"Will we be able to understand the answers your child gives?"  -  Again, no issue.

They failed to ask what turned out to be a very important question.   Can your child sit still and not play with our equipment?

Optometrical equipment is incredibly configurable to allow them to home in on the perfect prescription for your eyes.  This means that it has lots of switches and knobs.  Sophie, who is incapable of keeping her hands to herself, couldn't stop helping.

The doctor would move a piece of equipment to be in front of one eye.  Sophie would move it back to the center.   Repeat.

The doctor would ask Sophie the smallest line that she could read.  When she read it back the doctor looked confused and found that Sophie had switched the charts to a different setting.

The doctor would turn one dial on one side of the machine while Sophie twisted a different dial on the other side of the machine.

I'm guessing they don't have these problems with other children but perhaps now they will start asking this question ahead of future examinations.
