Lets see...to be warm hearted or coldly analytical on this theme? Ok...both.
Warm fuzzies...those that have the heart to give freely on demand without worrying about the motivation or circumstances of the request often feel good at being able to share and give. To help another out in time of need is noble. Of course one only knows their true motivations from the inside or why this particular person at this time. Obviously Ruff has a sense about this girl...and we all hope he is right on.
Coldly analytical...I think it is a general culture thing here where the gringos are looked at as money machines, and generous easy targets. Its not just the Delrey girls...its the Tico friends, the girlfriends, the taxi driver who becomes your bud, the shoe shine boyman on the corner. They are there because WE are. Do we help them when we give without conditions? Thats the tough question. In my years in Mexico, and now my going on 3 years living with a Colombiana...I never got hustled by a Mexican or Colombian woman. Most EVERY Tica and Tico I have known has tried to hustle me one way or another. I think it is indemic with the culture. Sorry...and in my opinion it is not attractive.
I have no problem with P4P and these girls making an "honest" living. i respect that more than women who PRETEND to be your GF...or even have sold themselves on the idea they could LOVE you...but are asking every other day or week for a handout. This happens primarily because we are hooking up with women of lower class and economic condition. In some ways this gives us a sense of power and superiority...because they are truly greatful (MAYBE) and will in turn treat us like kings. Whether this is bonafied, unconditional love...well, thats another question.
I have put my own long term GF to the test a few times. THe first time was when she gave up her free ticket and Visa to go to Las Vegas and maybe find work and have fun...versus stay with me in poor little Costa Rica. I told her in no uncertain terms that if she thought she would get to the states through me, she would find that completely impossible. She stayed and is still here...and has never asked me for anything more than $20 for one thing or another that was a neccessity. I know...this is rare. SHe works with and for me for which she gets funds and other benefits

.
I mentioned a long time ago on another thread related to this topic that my old Mexicana girlfriend in San Diego slapped me for handing her $70 she had asked to BORROW after we had made love. She couldnt understand why I would make her appear or feel like a hooker by doing that. Oops...bad timing and poor cultural understanding. Since then I have never handed a woman money after sex...even P4P. I lay it somewhere they can get it. These Ticas dont seem to care either way...which I find interesting...and not all that attractive.
