Today is my Dad's birthday. This afternoon I went to the shopping center downtown and
bought present for him. Then I take the subway train home. Sitting on the train, I thought my dad would
be very happy when I saw the present. At the next station, an old lady with two heavy bags got in the
train and stood in the front of me. She looked tiredly. I hesitated for a moment, and then offered my seat
to hers. The old lady thanked me a lot and seated down. Seen her smile, I felt happy. I will always be
ready to help other in the future.
