My good friend is a compulsive liar what can i do?

[matthew91]

Ok basically my good friend is a compulsive liar. He always has been, he lies to make himself look better. He has a relatively low self esteem and his lies are getting worse. His current lie is that he works as a security guard for our local supermarket. Its not possible, you need to be licensed and trained fully by law and hes only 18. Its sad because hes telling all the people round him about it and they believe him. He is a relatively popular guy who would do ANYTHING for a bit of attention. The worrying thing is that people trust him and I'm the only person realizing he just lies and lies. I need your help people, confronting him would be hard. i Once confronted him about a lie which i had hard evidence for and he tries to play the victim, he said he had a heart condition and i spoke to his parents about it and they were exceedingly confused.

Thanks
