Body language
Friendship

Body language between friends is typically more expressive and informal than body language in business. Trust within a friendship is conveyed in numerous different expressive forms. Like in business a handshake may be used on meeting but this may also involve clasping two hands around one hand or placing a hand on the shoulder etc. Body language which conveys trust between friends may also be significantly more expressive and physical than in business. Giving someone a pat on the back or a hug for example.

People's natural willingness to act openly and warmly with their friends who they know well can appear more genuine when compared with how strangers present themselves as trustworthy in a business context. This is because friends can read each other's body language and facial expressions more easily. This means that they are surer of what the other person means and find it easier to respond accordingly. The interaction is therefore able to be more open and this can be seen when observing friends interact. The communication whether in terms of body language or speech is freer and less constrained by a sense of formal etiquette.
