Some will understand what I say, some do not.
I speak the exact words you want.
Some words I speak however, you would like not.
For you to understand me, you shall study a lot.
I carry out your orders, exactly what you say,
I may make mistakes, but it is not my fault.
You will understand me maybe after an hour,
maybe after a month!
You will be mistaken, when you hear my name
I don't gather things from here and there.
No, that is so lame.
I do serious business,
Carrying out orders and translating is my game.
Can you guess who I am?
