thinking alot

as i watched clips from higher ground yet again..because i was bored and youtube is great but anyway..i was watching clips and theres this scene with a girl/student telling her teacher type person that she shouldnt expect to be trusted and learn someone elses secrets if she cant share her own..in a nutshell..interesting concept ive decided..its like what i heard a million times in all the social work classes i took..you have to know what your limits are in sharing things about your life to someone your working with..but its also pretty obvious that if you really know someone even in just a working relationship they will know when you are lying to them and it doesnt matter if its being done to protect them either..a lie is a lie..so i guess the next question is what counts as a lie? does it really go a bit farther than just saying its when you say something thats not true? do the rules change when you have to protect someone else? i dont know
