LOL!!
FORGET ABOUT PASSING LITTLE TINY MESSAGES IN PAPERS.
My friends and I do
WHATSAPP in class.
It is free, easy and AWESOME.
I actually have a digi number specially for whatsapp.
Actually it is to sign up for the cheap data plan by Digi. And also I want to keep my other number private. Hehe.
So do you whatsapp? xD
