There are about 130 different tribes, each with its own language, although English and Kiswahili are the official languages. There are coastal Muslims, urban Asians, farmers, fishers, businessmen, teachers, orange sellers, and lots and lots of children. Despite this diversity, some generalizations may be made. Tanzanians are a very friendly, social, open people. For many, it is more important to be welcoming than efficient.
Time has no meaning, and there is always room for one more.
School in Tanzania is not quite like school in the States. The idea was that, in addition to taking classes, the students would grow their own food and engage in other projects to help out the school. This perhaps was a good idea on paper, but made for some teaching headaches. More than a few periods were cancelled because classes had to weed the farm, carry water, collect firewood, unload fertilizer, or landscape the school grounds. Theoretically, the syllabus could be completed, but due to time and material constraints, more creative measures needed to be taken.
