My sister moved to the city in March and a flat with two colleagues.
The flat is small and old, however it is ten minutes from her office.
Her is four million dong a month, which is a third of her .
Her friend Mai chose a larger and cheaper flat in a district outside the city.
Mai pays two million, however she for ninety minutes every day.
That is three hours of her life on a bus, five days a week.
Last month my sister the cost of both choices.
Mai saves two million a month, but she also spends four hundred thousand on buses and eats out more often.
More important, she is too tired to study English in the evening.
My sister says the real price of cheap is time.
