My grandmother is more than ninety years old which makes her the oldest person in the whole family. Despite her old age, her memory is still fresh. She always tells us that many things used to be different when she was young. My grandma used to begin her day very early. She used to start her day at 4 o'clock while everybody else was still in beds. She used to do all the housework by herself. She used to make clothes for her children and as for her outdoor work, she used to raise some chicken and sheep and she also used to help the males to grow vegetables. There didn't use to be many pastime activities. Her hobby used to be listening to the radio. In the evening all the family used to sit by the fire in the sitting room where all the family gathered at night to tell tales or discuss family matters as weddings, harvest time or to assign the next day's work. When a member of the family was ill, she used to show him which herbs to use. She collected them from the near forest or from the mountain.
