Someone "is a liar", it's just not clear who. tu=you----you are a liar
a LIAR means a person that does not tell the truth about someone or something.

If you suspect that some is a manipulator liar then you are probably right. Get away from that someone as fast as you can!
If someone is a slime ball liar, it's best to stay away from them. You do not want to associate with someone like this, as it can affect yourself.

You are a story teller , liar,
