How many languages do you know?

I'm fluent in two, Indonesian-- my native language, and English. I learn Mandarin at school but I'm absolutely terrible at it, I got a brain of a monkey, I'm unable to learn a new language :-(
I understand some regional languages from here though, by learning how my parents and people around me communicate. I kind of understand Minangkabau, Palembang, Manado, and Javanese but I'm unable to speak with it :-(
