I must say GOOD JOB.

I am human I make grammatical errors as well. Atleast this level of attention to every slight detail in my post gives me an impression that EITHER you really have nothing to do OR you are really that interested.

I have not MET this person on Facebook like you meet a normal person : You search them you add them or you play games together.

Lets create Assumed names so its clear for you to understand :
Lets call my Car broking friend Mr.B the person that I know in person & who introduced me to him Mr.R.

So Mr.R is my real life friend, lets say more of a professional acquaintance.
Mr.R posts this picture of a very beautiful and expensive car on his fb cover shot with him in it.
I ask him is it yours where did you get it ?
He said he bought it with his own money that he earned.
I didnt believe I asked for proof, he introduced my to Mr.B by tagging him & Mr.B said yes he is an international car broker and he got him that car in finance.
Time went by i found Mr.B has a number of 'rich' people and agents/owners of various showrooms on his friends list who interact with him almost on weekly basis.
I eventually came to believe that this guy Mr.B is legit and after I saw another picture of Mr.R with his family in that car he bought.

Get the difference ?
