Use mirroring to build rapport
Another easy method to establish rapport with people is to mirror their body language and mannerisms. Try to mimic the bodily language and mannerisms of the person you’re speaking with while conversing. If they have their legs crossed, for example, sit with your own legs crossed as well.
Mirroring is a subtle form of engagement that implies you are interested in getting to know the other person better. You may create a sense of resemblance and relationship with others by making small changes to your body language.
