Do not tell a lot about yourself, womanizers are excellent psychologists, and can use new information for their own purposes. You won’t have time to blink an eye, but you will already get to the bait to the pickuper. Do not yawn, listen more, say less. Pay your attention to the little things, perhaps you will immediately catch the style characteristic of the pickuper and stop even before its start. The main thing, do not allow yourself to immerse yourself in a kind of state of error and relaxation, when this person can influence your thoughts and your opinion.
