Aladdin -  the diamond in the rough.

Aladin continues to dream big. Sadly though he is disregarded and viewed by the palace guards as nothing but a street rat until the day Jafar discovers he is the 'diamond in the rough'.  A pure of heart person able to enter realms foreign to him.
Would you know a street rat from a diamond in the rough?
I wouldn't either so maybe...
we should presume and treat every person as though they are the diamond in the rough.
