In recent years many flowers shops have been appeared in our small town. It
is common for people to buy flowers when they go to a gathering, visiting a sick
friend, or attend a wedding or birthday party. I still remember clear one day last year
when Tom, a disabled student, presenting some flowers to his mother to express
his gratitude. He owe his life to his mother's patient care. With her he would
not have had the confidence or the courage to fight her disability. As a
result the great effort he has made, he was finally admitted to a key university.
