Lying is bad because it destroys relationships by when you lie people don’t want to be friends with a liar. If you lie people who wanted a relationship with you might not want one with you any more because you're a liar. Also lying destroys relationships by when you lie people stop trusting you then more won’t trust you until not a lot of people can trust you any more.
Another reason why lying is bad because it can create a really big and bad habit. When you lie you think it’s ok because you didn’t get caught, but when you
keep on lying then you get caught you get in trouble and then you just keep on lying and it becomes a bad habit. When it becomes a habit you lie over and over and then it is impossible to believe you.
Lying is also bad because people need to trust you. If they can’t trust you you won’t have any friends, anyone who trusts you, anyone you can play with or have fun with. If people don’t trust you, but you auctuctly tell the truth they won’t know because you have lied to them so, so, so many times before.
In conclusion I think lying is bad because it destroys relationships, it is a really bad habit, and people who trusted you before won’t trust at all ever again or for a little while
