I took a trip back to my primary schoola couple of years ago. My original stint in primary school was quite memorable for me because i was almost always the youngest in my year and subsequently always close to being the smallest boy in the class/year/grade. This resulted in me being bullied at times. My return was awesome, i turned that crappy memory around when i went back. I have to say i must have stolen the lunch money off 20 of the biggest kids at the school. It wasn't about getting money (i handed it to the smallest kid i could find, I'm kinda like robin hood) it was more about having my day of superiority. Try it sometime, You'll love the experience.
