From Personnel to personal

It is not always easy for a person to distinguish between the differnence between two different indenties he has.( By he , I also mean himself/herself/she/ it). One is he as a person, an individual and the second he is personnel as in one who works for companies. Its interesting that people often mistake each other. Even I did it this morning! A monkey is off my back. As Sodhi (My Advance course leader) said: You don't know your a_ _ from the h_ _ _ in the ground!
