a little miffed..

How can Kenneth's credit score be 60 points higher than mine? Seriously, I was going through the things I had listed on mine and everything said on time/good payer, etc. Not a single negative thing. Is it because I am the one who bought the cell phone plan and did the legwork for vehicle purchase? Cause I know they checked my credit then...but seriously. And why would your credit score go down when people check your credit? It seems so arbitrary.
