She got married yesterday and graduated out of Theirry's class today.  Or she would have, except she has moved to Daoula with her new husband.  His Sunday School class is for students 17 years old up to 30.  At which time you advance to the men's group or the women's group, if you haven't already graduated out by marriage.  Young people don't think about marriage until they are 25 years old or older.  It's just not done.  And for a young man, it simply does not enter his mind to think about his future wife.  Right now he's getting an education and preparing for life.  Time for finding a wife later on.  It's not a bad system, really.
