No tuition again

cancel tuition today again.. haizz...
because of I forget to bring back the reference book to home.

so sorry teacher.......
you are very busy, fully book and you take some of your time to give me tuition class,
but I made you have to cancel class today, wasting your time... Sorry~~

I think 'time' for all the teacher is very precious,
for teachers time=money, money=time..

Cancel a class then they will lost their money,
I don't know how many class I had canceled...
I afraid this cause she do not want to teach me anymore...
