My First, and Hopefully Last Security Problem!

2 kids just tried to rob me! Like 30 minutes ago in Portoviejo. They couldn´t have been more than 12 years old. Those little $%"& didnt get anything though. I´m so mad at myself for even letting it happen because I felt like something was wrong and I should have ducked into a store, but instead I kept walking over a bridge even though they were trying to talk to me and followed me when I crossed to the other side. Then the one tried to yank my purse off of me, but it didnt break and I hit him and yelled at him. So him and his friend just ran away. It was on this bridge and a ton of people were around. I looked for a cop, but didn´t see one. So another attempted crime goes unpunished...I was shaken up at first, but am settling down now that I´m in an internet cafe where I feel safe. Hopefully this is the first and last incident of this kind...
