A typical man will have no qualms hosting another one who has just come back from a local or overseas business destination to some nyama choma and a drink. He may not have any immediate plans of going into business, but he will listen, nevertheless, and note important facts and figures as they are narrated. Such an encounter will definitely cost the host money, an investment in knowledge that many women can neither understand nor stand!
On the other hand, a woman will save a tidy sum of money and use it to spruce up her house with new décor, cups, blankets and so on. She may also go on an impulse buying of new clothes and shoes while her husband's major plans stagnate on account of school fees and other overheads. A male spouse to such a woman may blow his lid off at his wife's apparent "insensitivity" and lack of "consultations" in her "superfluous" purchases while "big issues" dog the family.
