Here is an easy way to remember some basics of body-language and non-verbal communication.
In order to soften up someone you are talking to, just remember “SOFTEN.”
S – Smile (it is amazing what a genuine smile can do)
O – Open posture (not holding arms in front of your body)
F – Lean forward slightly (it shows interest)
T – Touch (depending on the circumstances, most experts recommend a light touch on the arms)
E – Eye contact (always essential… just don’t stare)
N – Nod (if you agree with something, show it)
