It seems to be a part of human nature, once they know you a bit, the light goes on in their head and they see a chance to "use you" as an instrument to "help them" solve a certain problem, and after a while, it could be an inconvenience, {usually turns out to be more complicated than originally thought} or even something where you could get in a little trouble if a little mistep.Also, they "invite you" to activiities that are unGodly.Usually it's better off you DON'T get too friendly with most, they'll eventually have the "troublesome request."
