i am not exactly in a good mood today. i cannot find the book which i bought for my student. as a result i had no mood for tuition. and my mother took over for me for one lesson.haha and i am quite grateful to her for helping me.

and i always thought that family members should not be too calculative about money. fine then, if you wanna be calculative with me, i shall calculate too. it is actually quite saddening to know that family members actually wanna calculate money with you.
