Greetings etiquette
In most cases, a handshake is appropriate when men greet each other. Handshakes are often energetic and linger throughout the greeting process and, in some cases, the entire conversation, which may include walking where it is customary to continue to hold/shake hands. When shaking hands, it is customary to grasp the right forearm with your left hand as a sign of respect/deference. A low hand slap is common in casual situations. Many men also share a light touch of the right side of their forehead to the left side of the other person's forehead.
In most situations, a woman should greet another woman with a handshake and/or a nod of acknowledgement. When shaking hands, you can also place your left hand over your right elbow/forearm to show respect. Women frequently hold hands with other women, and the handshake is frequently extended into this hand-holding. Close friends and family members typically hug and kiss each other on the cheek, alternating sides. If you're unsure what to do, simply follow your Rwandan counterpart's lead.
Greetings for Men and Women - Appropriate greetings vary according to the nature of the relationship and the region. A handshake is usually appropriate, but if the woman does not extend her hand, a bow or nod of acknowledgment will suffice.
