The World Stone

Andrew/Andrea is a typical freshman in college, he/she is 18 and on heading home after finding out that there boyfriend/girlfriend has been cheating on him/or her. As he/she comes to a street Andrew/Andrea notices a light, at further inspection the light seemed to be changing colors. Andrew/Andrea pulled over and examined the light. It was resonating from a small stone that appeared to be almost the same kind of stone found normally on the street except the light. Andrew/Andrea decided it was interesting and warranted more inspection.

First decision: who are you - Andrew or Andrea?
