Tip: to understand any person
let other one speaks more about itself , give a space to them to talk freely and just observe.
yes , but do not make fun or misuse of feelings or things that shared during discussion.
at the end of the discussion ,you will get to know what kind of person the other one is.
this is a small tip or say suggestion from very small person.
i tried and succeeded all the time , i hope it will help you to understand people more quickly.
