The Pattern Of Three

Before, there was only us,
in which you, I truely trust,

Playing the never ending game,
loosing twice, I thought I am to be blamed,

You won again, hmmm something does not make sense,
"Just my luck..." you said, on your defense,

Not for long, I found out,
there was three of us,

You made a bet again today,
certainly tomorrow you will pay,

You tricked me; He and I...tricked you,
playing this game...surely your are new,

Softdrinks (Pepsi) for me after class,
Please be on time for my patience will not last...
