One more thing to learn

The word "santaş" is incorrect. It is "şantaj" which means "blackmail"

And "şantaj yapmak" means "to blackmail"

Sen başkasın = You´re different (most likely in the context it would mean "You´re not like that/like them/like him"). 

Ben sana güveniyorum = I trust you. 

Ben sana inanıyorum = I believe you. 

Güvenlik = security, you can see this word in many places in Turkey. 

/Rob

please could you give me the example where I can see Güvenlik?

Thnx. J.
