you are an individual and we both dont know eachother right, still just for sake i m giving you my family’s reference for your help isnt it, and you are right in these days we cant trust anyone, 
when i m trusting a unknown person, you must show some curteousy in return
Just for your help coz people are strange and since its a new place for you thats y atleast you will get some friends and atleast someone to talk and have atleast someone to care about you.
