" But whether you’re a memoirist or not, there’s a psychic cost for lopping yourself off from the past: it may continue to tug on you without your being aware of it. And lying about it can—for all but the most hardened sociopath—carve a lonely gap between your disguise and who you really are. The practiced liar also projects her own manipulative, double-dealing façade onto everyone she meets, which makes moving through the world a wary, anxious enterprise. It’s hard enough to see what’s going on without forcing yourself to look through the wool you’ve pulled over your own eyes…For the more haunted among us, only looking back at the past can permit it finally to become past. "
