Literally everybody that ever existed has told things that weren't entirely true. Wherever its an exaggeration, misunderstanding or just something they misremembered, all of these will have occurred to everyone multiple times throughout their lives. By this truth, you cannot trust anyone. Which might be true - but definitely isn't healthy either. (It's also entirely unrelated to what I interpreted your argument to be, previously)
