In general, Kenyans give gifts for events of significance in a person’s life or days of religious significance.Gifts should be nicely wrapped, although there are no prohibitions concerning the colour of paper. In rural areas, gifts of sugar or tea are quite common. Gifts should be given using the right hand only or both hands. Never use the left hand.
