The problem with telling a lie is that it sets off a chain reaction. Once you utter the initial falsehood, and questions begin to arise, you're compelled to continue lying in order to validate the first lie. This creates a vicious cycle, a never-ending rat race that's both overwhelming and degrading. Ultimately, the truth will inevitably catch up with you, exposing the web of deceit and leaving you to face the consequences of your dishonesty.
