Do You Trust Your Friends in Dubai?

I believe that if you get to my age and you have made a kept a very clean reputation for yourself, then people are always still going to tear you down. People are always looking to cheat me, in which case they may speak bad about me. But whatever it is, I have friends in Dubai who I trust very much. When I get approached by certain people, hi, my name's this, I'm from this certain family I'd like to meet and talk to you. I say, are these people trustworthy or not? My friends are very trustworthy because I've known them for many, many years."
