Well done that teacher.
Sadly it’s common to pass children around in Africa and anyone saying the child is coming to Europe are trusted as it’s seen as the land of milk and honey. I spent 4 months in a small African country, no war, no famine. I was offered several children and told I could send the child to school but they could also act as a housemaid. I was considered a bit ungrateful when I refused. At least 2 women asked me to get them into Britain and employ them illegally. And 4 men asked me to marry them, as in “ hello, Madame, how are you today, where is your husband today? ( no husband) Will you marry me, or I think we should marry”
Family life is very fluid, grandchildren live with grandparents as company and to relieve the burden of food, school etc on the parents. Parents go off “ travelling” which is looking for work and children are left with various relatives.
Mo Farrah’s mum would have believed he was going to be educated, cared for and be able in time to financially support the family back in Africa.
