Why Would I Lie About A Thing Like That?

I was recently updating my LinkedIn account.  While doing this I came across the name of an employee that worked for me 6 to 7 years ago.  Young kid that I like a lot.  He had tons of potential.  So I sent him the message to have him join my network.  Pretty straight forward.  Then I noticed he had listed himself as a VP at the company we worked at.  Unbelievable.  Maybe I am too honest but it just blew me away that he would lie.
