Why = Mengapa; kenapa
"Mengapa" is formal and standard in Indonesian while "Kenapa" is more informal and is used in conversation.
when you're a police officer on a case hahaha
That's better than the other version :
"Shoot first, ask questions later"
It feels odd to say "why and how". It is more typical to say "how and why". It is also more logical.
kenapaaa dan bagaamana....that's yang aku dengar. seperti suara robot
