Maybe it is someone from your home village, someone you grew up with. Or maybe it is someone from school, or from work. Or maybe you found her at the local church. She is pretty, she is healthy, she has demonstrated her ability to cook, she’s interested in having children. You have found a keeper. As you get older, she may not be be as you remember her, maybe she is exhausted from her work all day just like you. On weekends you find another woman who can keep you entertained. Or maybe you find this behavior in your peers disgusting and you remain faithful to your wife (there is a clear culture-clash going on, but I will defend the statement that here, adultery is a much more discussed affair, and though I don’t know the levels compared to the US, it seems much more prevalent here, but maybe it’s only because it is discussed so much).
As you become more and more experienced you keep moving from job to job, not settling into a career very early. First, you may decided to buy some land in your home village, or somewhere in your ancestral homelands based on tribe, near your family. There you can set up a farm, build a nice permanent home, have your family stay there, near to your relatives who can help out with the children. It seems that if you are a government employee you especially move around to wherever the government wants you. But instead of burdening your family with constantly moving, they stay on your land, work it, develop it, make it profitable as well so that you have a dual-income and have become part of the landed class.
You may live in Nairobi however and may keep your entire family there. Life is becoming very Westernized in Nairobi, and that is where you want your family, not out in the mashambani (fields) with the washamba (slang: derogatory for countryfolk). You may save up to buy an automobile, put your children through the best schools possible, focus on getting passports (much more expensive here than in the US). Hard work can pay off in the private sector, which is much less scrutinized by the Western politicians. Nairobi is the path to success and though it may be expensive, it will be worth it in the end. Just keep working. Visit the relatives in the village for the holidays. When you get there you may feel at home and realize you have missed the place, maybe you will look into property after all. Or, maybe you feel distant, having nothing in common with your friends anymore. You’ve been the city, you’ve seen the money and power there, these people don’t really know where Kenya is going.
