Last Saturday I went camping with several friends. In the later afternoon, we put up our tent in the middle of a field. Then we cooked a meal over an open fire. The food smelt good. After a meal, we told story and played games by the camp fire. At the eleven o'clock we felt tired but we put out the fire and got into our tent. Lie in our warm sleeping-bags we slept soundly. At midnight one boy woke up and began shouting. The tent was full water! We got out of our sleeping-bags and hurried outside. It was raining heavy. A stream had formed in the field, that wound its way across the field and flow under our tent.
