　　Always play in a safe place. A park is a safe place because there are no cars or trucks. But don't talk to anyone you don't know. Never go with a stranger into motorcar. Before crossing a road, stop and look both ways. Look left, look right, look left again. Keep away from houses or buildings that are being built or knocked down. Something might fall on your head, or you might cut yourself on broken glasses. Medicines or pills can be dangerous. Never eat any pills or medicines you find in the cupboard. Wear a life jacket whenever you go out in a boat. Even if you are not in the open sea, and the water is not in the open sea, and the water is not deep, you should have on your life jacket.
