Sam is nineteen years old. He is a programmer. Sam has got a family. His favourite hobby is gardening. Now he is going to plant some flowers. He wants his garden to look nice, so he plants flowers, waters them and digs weeds (выдергивает сорняки). He enjoys his hobby because he can see how beautiful his garden is and gardening helps him to stay physically fit. I like gardening too. I usually help my grandparents who have got a garden.
