Narrative:

Ground asked me to take runway 31R for takeoff prior to taxi. I refused and asked for runway 31L. Runway 31R is a 4000 ft runway and runway 31L is 7300 ft runway. I was puzzled that ground would ask me to take a much shorter runway than was available. I let this distract me. Ground then gave me instructions to taxi to runway 31L. I wrote it down incorrectly. I had second thoughts and hesitated taking runway 31R for taxi, but received nothing from ground and traffic was clear. I was corrected by ground immediately but told to continue to back taxi on runway 31R. Perhaps ground realized he was not clear in his instructions. I should have asked ground to repeat the instruction.
