12. “Glove” handshake
If a person takes your wrist with their free hand, they are showing that they can be trusted.
13. Handshake with a palm facing the ceiling
A palm on top of someone else’s hand signals that a person is feeling sympathetic. But this is true only if a person does it instantly. However, if you have held the handshake for some time already and only then does the other person put their hand on top, this may be a sign that they want to tell you who is in charge here.
14. Handshake with a palm facing the floor
If you are holding someone’s hand from below, you want to tell them that you are ready to help.
15. Handshake with a touch
People sometimes touch others with their free hands. They can touch the forearm, the elbow, or the back of the other person. Such an invasion of private space means that a person lacks communication. The closer the touch to the torso, the more the person needs company.
