In communication Rwandans start with background information, supportive arguments and sometimes examples before they get to the point and it is believed the best communicator has to lay a very good foundation for their message. Going directly to the message would either mean you not a good communicator or in some instances it could be very rude. That is why in meetings very often Rwandans start with brief social /family talks before diving into the business agenda.
Though Rwanda neighbors Uganda, Tanzania and Congo which are reasonably expressive culture Rwandans are noticeably non expressive. Rwandans rarely express their utmost anger nor happiness. Therefore if you give a gift to a Rwanda do not expect a loud shout expressing happiness and gratitude. A simple "thank you very much" will be enough for them to express their deepest happiness. Likewise, if Rwandans are angry they never yell.
Please note that this do not apply to all Rwandans. Some people will communicate differently depending on their education background, community and individual personalities.
