Too many horseflies<br>Anna went to a house on a beach for a bbq. When she got there on the lawn she was playing. All the sudden dozens of horseflies were on her pants biting her. Anna kept spraying bug spray to kill them but nothing worked. So she had to just go home instead.
There was grass on the beach.
The phrase "on the lawn she was playing" implies the presence of grass, as lawns are large patches of grass in front of and/or behind houses. However, beaches do not usually have grass growing on them, or if they do it is usually overgrown and not grass one can play in.
