A lot of discussions arise because people do not know the meaning of the words/expressions or do not use the words/expressions technically; sometimes words/expressions are synonymous, but are used to mean different things. Even sometimes different people use the same word/expression to mean different ideas. So I would like to know what do these words mean for you; and which is the connection among them: Defense drive behavior; weak nerve; threshold; suspicious to stranger; lack of balance; anger; fear (fear biter); cowardice; braveness, balance, confidence.
