Our School System and Our Customs

Hi dear friend!
How are you doing? I hope you are well, by the grace of God.
What about your friend? I hope she is doing fine now.
I hope that your brother and his family are also well.
I am writing you to tell you a little about our school system and our customs. It is true that you are not a student, but you have to know them.
Africa has its school system with its own reality. In fact, school lasts too long in the French-speaking countries where am I from.
Ivory Coast has a few universities with their own problems…. What about your schools? [Or your could say "What about yours?"]
In Africa, it is difficult to find people between 20 and 25 to date, because our custom is that they live with their families at that age.
Enough with my story, so let me know what makes you happy.
Write to me soon!
Your friend,

Julius

*Good job, Julius!  

One note: In English, a "custom" is usually something that everyone in a society does as an unwritten (or written) rule.  For example, shaking hands with someone when you first meet them is a custom. 

I changed the sentence about dating because the the fact that young adults live with their families is the custom, not the fact that it's hard to find people to date.

I hope that makes sense!

Keep writing.  :)
