ie: u blanja me lunch at sci canteen. i will blanja you lunch in sch or at the grinning gecko or anywhere else where its not too exorbitantly expensive.

ie2: u spoil my dae, i will not get back at you. I'll just complain here, make some noise, but i wont do anything to you. i believe in karma, that ji suo bu yu, wu shi yu ren (translation: do onto others what you want others to do unto urself).

Kindness / Goodness makes the world spin merrily. Do more good deeds, make more people smile, and you will feel good too.
