This has been happening outside the continent, I mean in Europe, America and Australia but right here in Africa. It is a different thing, it will be referred to as sacrilege (heard this word for the first time when I was watching home videos yesteryears) but right before our very own eyes, it is happening.
A Malawian women married her own son, her reason was simple. She said, she has spent a lot on her son's education and for that reason she want to enjoy her hard work. She claim that other women should not been getting anything from his son since they never contributed anything. She is 47 years while the son is 30 years, this means she gave birth at a very tender age and she has gone through a lot to see him succeed.
Most people are not happy with her decision and believes she has bewitched her son in getting him to marry her and they are currently living together.
