Wish upon a star? Sure, why not? Unless you decide to be an idiot and post online that you wish the star to fall on someone you hate to crush/burn them. And in particular, if you happen to have a license to practice medicine as a medical doctor or registered nurse, and have taken an oath of service directed to health care. And several other restrictions such as yelling fire in a crowded place where no fire exists.
A FL RN has learned the hard way that she cannot wish bodily harm to another person and hope to retain her state license.
These are the consequences [wages, it you will] of hate. Keep it to yourself.
