My mother eyed me with suspicion.I dared not look at her.Knowing that I was late from school five days in a row，I could not offer an acceptable explanation.However，realizing she had little choice but to accept my explanation that I had extra curricular activities every day and arrived home after 5 p.m.，she told me that dinner was in the refrigerator and to warm it up in the microwave oven.She had to rush for her night work at the local clinic.
    After our dad passed away in an accident，my mother became the only breadwinner.I was the eldest among the four siblings （兄弟姊妹）and it fell upon my shoulder to ensure that they would become responsible adults.Aside from helping Mother with the housework，I regularly coached them in their studies.Thankfully，never once did I have to raise my voice or force them to complete their homework.But all of us missed Dad deeply，who was a model father and husband.Mom had never recovered from the tragic incident.
    However，she managed to pull through to raise us and secured a job at the clinic.It was very tough on someone like her who had never worked before in her life.But money was scarce and there were five mouths to feed.We stopped dining out and had our meals mostly at home.We basically lived from hand to mouth.That's when it dawned on me that I had to do my part for the family.I knew Mother would not agree but I threw caution out of the window and managed to get a part-time job at a fast food restaurant.I worked three hours a day and managed to bring home money so that my siblings and I could go out for occasional movies or meals.
    I was sure Mother suspected something wrong.But she could not quite point the figure to the source of her suspicion.However，I was awfully guilty and had to constantly reassure （寬慰） myself that contributing financially to the family was the least I could do to lessen my mother's burden.
