It was raining hardly outside， which made it difficult for me to go home for lunch． Just as I was wondering what I should eat at noon， I saw a familiar figure passed by our classroom． I rushed out and it was my mother， already in fifties， which brought me lunch in spite of the heavy rain． In China， many parents make great sacrifices for our children． But what had the children done in return？ All too often， most children just take it for granted that their parent should serve for them unconditionally． My dear mum or dad， thank you very much for bringing me up． How shall I do for you？
