Here are some ways it can be used:
* "You think you're going to be a famous musician? Get real! It's incredibly difficult." (This suggests the person is not being realistic about their chances of success.)
* "Stop dreaming about winning the lottery. Get real, it's never going to happen." (This emphasizes the need to focus on practical matters instead of unrealistic fantasies.)
* "Come on, get real! You can't expect to get everything you want." (This encourages the person to accept the limitations of reality.)
The tone of "get real" can vary depending on the context. It can be said in a friendly way, as a piece of advice. It can also be said in a more forceful, even rude way, to express annoyance at someone's unrealistic expectations.
In short, "get real" means to be honest and practical, to acknowledge the truth of a situation, and to stop living in a fantasy world.
