Barbecue In The Park

    Last Sunday, my friend and l went to the park because David's family invited us a barbecue party in the park. We lived nearby we just walked there.
   When we got to the park, there were not many people. David's family was already there. They arrived there early to get the best picnic spot with an electronic grill nearby.
   When we arrived, they were cleaning the barbecue. After making sure the barbecue was clean, they turned the barbeque on by pushing the button. The electric stove turned on and the metal plate became hot.
    David's mother put some cooking oil on the metal plate, and after that she put some sausages, beef steaks, and some on the barbecue. Meanwhile, David's father was preparing the bread, butter and the drinks.
     While waiting for the meat to cook, David and l joined others boys playing football. When we go tired, we stopped and enjoyed the sausages, steaks and some cold soft drinks. 
     The food was delicious. I think David's mother is one of the best cooks in the world.
