Over the past two months, a group of secondary school students have taken turns to clean private cars early in the morning before going to school.
Every day at dawn, two students from a Form H class at Kung Lee College have headed for a block of luxury fiats in Tai Hang Road, to wash and mop private cars.
The students were not trying to make a few dollars for pocket money--they were trying to help a classmate.
This classmate's father, who worked as a cleaner at the building, was admitted to hospital recently with a serious heart disease.
His daughter, left by herself and with no other relative in Hong Kong, faced the biggest problem in her life.
To help her pay the medical expenses, the girl's classmates volunteered to help her by doing the cleaning job on her father's behalf.
However, the students' enthusiasm failed to change her tragic fortunes--her father died.
The students then chipped in with their savings to pay for the funeral expenses. They also called on residents of the building and asked them to contribute.
In addition, they took turns in taking their classmate to their homes to comfort and console her.
However, she recently returned to her home--a seventy square foot cubicle in the basement of the building--as she wanted to be independent.
"Although I've come across much misfortune I've not lost hope. I want to be a useful person and I want to find a meaningful job, "she said yesterday.
She said she had no immediate plans, although her ambition was to continue her studies and become a nurse.
