Handshake with both hands

All over the world, a sign of heartiness and sincerity is considered to be a handshake with both hands, accompanied by a direct look in the eyes, an open smile and a loud rendition of the interlocutor's name. Often a handshake with both hands is also accompanied by a question about the state of health and affairs of the interlocutor.

Handshake with both hands
Such a handshake enhances physical contact on the part of the initiator. The initiator gains control of the situation, since it immediately limits the movement of the interlocutor's right hand. Sometimes such a handshake is called a “political handshake.” The initiator immediately tries to convince the interlocutor that he is a sincere and honest person who deserves every confidence. However, most often such a handshake produces the opposite effect. The interviewee immediately begins to have doubts about the intentions of the initiator. A handshake with both hands is a miniature hug, so it is only acceptable in situations where a hug is acceptable.

Ninety percent of people are born with the ability to strike a direct blow with their right hand in order to defend themselves. A handshake with both hands restricts the freedom of the right hand, and hence the ability of the interlocutor to defend. That is why it is never possible to greet strangers and unfamiliar people. A handshake with both hands is appropriate only if there is a close emotional connection - for example, when meeting with an old friend. In such circumstances, the issue of self-defense is not so relevant, and the handshake will be perceived as a sign of sincerity and friendship.
