These part time party girls come to the DR with the " what happens in Vegas , stays in Vegas" attitude which has been told to them is "ok" once in a while . Initially its just to have FUN, Dance, eat, drink, watch some shows at the AI , Mingle , learn a little about the Culture..
But females are not wired like most Men, and if it does get physical, many of them can not separate a one time fling, with Real Emotion..that is where the real danger starts . And it does not matter that Fausto has no means of monetary support, or is living at home with 3 other much younger siblings ..They went too deep, and now they Rationalize it that there is " something there" , they cant explain it , but there is something there.
When you see it happening to one of your own family members , you kind of get a really good look into the psychology of it.
Many times it involves a recent breakup that sparks this bad decision. Not a good time to go on vacation to a place where there are absolutely no rules.. Confusion does not set in until its much too late..
They usually do not even hesitate to help him out financially , first couple times its a given..only when the stakes get higher do they begin to question it, but even then its easier to throw more good money after bad, than to admit you just messed up.
