Mary: Dad, it's so hot. I want to go swimming.
Dad: You can go to the swimming pool. It opens from 12:00 to 17: 00 in the afternoon.
Mary: Ok, I will go there this afternoon.
Dad: You'd better not go swimming alone. And don't have a heavy lunch before you swim. It's dangerous to swim when you are too full or too hungry.
Mary: I know. I will go with my friend Linda and have a light lunch.
Dad: Please follow the instruction and advice of the lifeguard.
Mary: I will. I never run near the pool. I never swim in the deep area. And I never dive in the pool. Don't worry about me, Dad.
Dad: Ok
