The definition of beat about the bush is:
(verb) to discuss a topic without being specific about anything
Our boss always beats about the bush when he has to tell us bad news.
Daughter: Mom, can I go camping with Susan’s family?
Mom: I’m not sure…..
Daughter: I really want to go.
Daughter: All of my friends are going! I want to go too!
Daughter: Stop beating about the bush and just tell me if I can go or not!
