it doesn't hurt to (have or do something)

It is or may be good, pragmatic, or beneficial to have or do something. (Also used in the forms "wouldn't hurt," "couldn't hurt," and "can't hurt.") I get that you like doing things your own way, but it doesn't hurt to have a helping hand now and then. I know that the managers are trying to cut costs, but it wouldn't hurt to treat the staff to lunch now and then. I'm sorry for just showing up here, but I know it doesn't hurt to have a friend when you're going through something like this.
