imagine a guy you never talked to but is not a stranger families know each other and you bump each other at wedding parties..
he acts like he is intrested in you but how to know if he only does it to make you feel that way and be attracted orso and he is using that "energy" to boost his ego, motivation, to feel good about himself? do guys do that acting like he is curious about your intentiosn but it's only for rising his self esteem
