True, there are no verb conjugations in Indonesian :)
Some of the pronoun "you": kamu (informal, intimate) Anda (formal, polite)
"kamu" is intimate. Use it only when you're talking to your friends or to a child, even your kids.
When talking to a stranger, to someone who is older, or to someone that you've just met, use "Anda" instead.
I drink (...) = Saya minum (...) You drink (...) = Kamu minum (...)
I don't drink (...) = Saya tidak minum (...) You don't drink (...) = Kamu tidak minum (...)
I don't drink milk. Saya tidak minum susu.
