Handshakes can have different meanings based on their characteristics. A firm, brief handshake that is accompanied by friendly body language may convey that the other person is genuinely interested. A handshake that is too strong might suggest that the other person is trying to dominate the interaction. A weak grip might suggest disinterest or nervousness, while handshakes that last too long or involve standing too close may result in feelings of awkwardness or discomfort.
