no u cant tell, r u crazyy? women have perfectedd the art of lyingg. it comes naturallyy. BUT we onlyy lie when we kno ur lyingg 2 us. so the real question is: can u tell when a MAN is tellingg the truth?
Hell yes. It is so easy to determine when a woman is lying. I enjoy mind fucking my girlfriends at first. Letting them think they are lying to me - playing along with it - and then showing myself painfully confused as I "Stumble" upon their lie.
Have you ever read any books on body language? I do admit, it is much easier to figure out if a woman is lying if you have spoken with her on several previous occasions.
You have to obtain a baseline for how a person acts before determining the validity of their words.
