"يوجد شخصان فقط في حياتك يجب أن تكذب عليهما الشرطة وحبيبتك."

Simplified Meaning:

In this saying, the idea is that lying is generally bad, but sometimes people make exceptions. The two exceptions mentioned are the police and your girlfriend. The idea is that you might lie to the police to avoid getting into trouble or to protect yourself. For instance, if you were speeding, you might not admit it to avoid a ticket. On the other hand, you might lie to your girlfriend to keep her happy or avoid hurting her feelings. For example, if she asks if you like her new dress and you don't, you might still say you do because you don't want to upset her. This saying suggests that, in some people's view, these two situations can be a little different from others where honesty is more important. However, it's important to note that this advice can be risky because trust is key in relationships and the law, so use caution with such lies.
