I did it, told my form class i resigned :) I mean, its nearly half a week after i tendered, and since STU called me to say they received my resignation notice, then it's final and settled.
I have been greatly blessed by two 4Es to call my own. Two Prefect Exco batches that i groomed.
I think I've achieved what I set out to do when I wanted to teach.
And so a chapter ends, and a new begins :)
