Vegans Die Early

How can I approach a person who lies a lot?

I have an “ex-friend” who lies A LOT about EVERYTHING.
For example, in class we have to say what we did on the weekend and she lies about that even if I was with her or she told me something else earlier.
She also said a lot of very bad things about me, including that she ‘imagines how i’m going to die every day’ then lied about it after when I asked her.
On top of that, she copies everyone around her. I became vegan a couple years ago, and she did too. I like a band, and she likes them too. If I don’t like a band, she doesn’t like them anymore. She copies my friend’s jokes too, and the way she writes when she makes posters.
Now she’s making it seem like I did something wrong, and it’s not fair.

You can always tell your friends what you are going to do in advance and then let her fall into the trap. Sending them a letter that is postmarked before the thing happens is almost as effective as well. I wouldn’t recommend this ordinarily, but she insists on wishing you harm (even in a passive way) she should find out what kind of consequences her falsehoods reap firsthand. The very best thing of course, is to have all of your friends work together to plant multiple opportunities for her to fall into the trap, but I don’t know how much loyalty you command now that your ex friend has cast aspersions on your own reputation.

Early human ate meat, not vegetarian or vegan, right?
