each person does the amount of lying that is right for them. you have to know yourself and fulfil the amount of untruths that your constitution requires.
for me, lying created just the right amount of problems, and what you saw was just one of my four or five faces - each real, each with different needs. the only dangerous lie was one that asked me to compress myself down into a single convenient entity that one person could understand.
