"when you tell one lie it leads to another"

this means that when you tell a lie you are guaranteed to tell another, and another, and another. therefor this means that you should always tell the truth. for example when i was in seventh grade i lied on my essay and plagiarized. the easiest thing would have been to just do my own work but i chose to cheat and i got into serious trouble, so now i know to always tell the truth
