I agree with you @Boris. This is [mostly] an African curse. The minute you look at your kids as a retirement plan or your relatives as a mobile ATM then from there things can only go south!
The sense of entitlement sometimes is baffling!!! You are my cousin/uncle/sister/brother to the uncle of my aunts bla bla bla and you are doing well. Why aren't you paying school fees for my kids??? Why are you surprised when my kid "passes" and I show up at your house with a list of all the requirements from fees to uniform to books to shopping?? And how dare you ask me how much of that money I can raise? Aren't you the big shot. You still want me to contribute my kidogo money to this??
These stories are all over. A friend was explaining to me today how a relative has cost him so much on investments/businesses he runs down and just walks away without looking back! The fellow then shows up after sometime as if nothing ever happened expecting more assistance! Being an African, I have also had an experience with this.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
