4. Foot Tapping
This could mean a lot of things. Some people do naturally tap their feet without realising it but usually it’s a sign of nervous anticipation. You usually see football managers or Formula One team bosses tapping their feet. This shows an excited apprehension as to whether the team will finish well or not.
If the person is sitting with their feet crossed at the ankles then it generally means they are at ease and comfortable with you.
