“Easters”
"Easter Eggs" are used to describe hidden surprises that you can uncover in games or applications after typing certain combinations on the keyboard.
In St Nics, teachers often receive "Easters" from their students too. In their assignment. While some teachers frown at the unnecessary doodling on the papers, I usually can’t help but to respond to those drawings by adding more graffiti (sorry, girls).
hmm..
Yea. Nice to meet (you) too.
Asking me to take the pledge.. why eh!
Yah yah..

Oh well, my students cute eh? Seriously, such things break the monotony of marking. =)
