If you are sending a letter to someone in Ghana you need to have a post office box number as letters are not delivered to people's houses. If you addressed a letter in the way you have written I don't think it would get to your boyfriend.
Then how would i write it. I have no clue, this is how he told me to write it. I don't know if you know the guy i am talking to his name is Sando Johnson he lives in Ghana. If you do can you please find out out to write his address. If i talk to him any today i will ask him but if not can you find out. I would greatly appreciate it. Thanks.
