I spent a year in Chile. 99% of the girls I spoke to were friendly and polite. Some told me that they had boyfriends. Most gave me their phone numbers and email addresses. I wasted a huge amount of time emailing them, and calling quite a few. Many exchanged quite a few emails with me.
What came of all this? One or two actual meetings, one girl friend who spent 10,000€ of mine on plane tickets and other things before ditching me.
Please, please, please if you are not interested, just say so politely. Don't satisfy your ego by making huge collections of suitors you really have no interest in. That practice, Latina hobby number one in Chile, hurts terribly, getting our hopes up only to be disappointed. Gringos have feelings, too I will never go to Chile again.
