"I go home."
I find that I'm learning by the process of elimination and therefore wondering if I'm really learning.
I think you are really learning.
It reminds me of Sherlock Holmes :
How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?
There are two levels of developing vocabulary: recognition and recall. You have to go through recognition first (what you do when you see the answer in a list) in order to eventually reach recall (when you can think of it without seeing the list). It's just a step in the process.
If I've understood well, this is a little bit like in French. In French you usually say "je rentre" (literally "I go inside again" or, a little bit less literally, "I go back") to mean "I go back home", you don't need to say explicitly "home", it's implied. I think that the idea in Indonesian is more or less the same: if you don't say where are you going back to, it is implied that it's to your home.
