    Imagine you open a door and find a surprise. 'たら' can show this kind of discovery. You do something, then you find out something new.

    This is different from other 'if' words. It is not like '〜と' which shows things that always happen. It is not like '〜ば' which talks about general ideas. It is also not like '〜なら' which gives advice. '〜たら' always means the first thing must finish before the second thing can happen.

    Don't use this when the second action happened before the first. For example, you cannot say "If I go to Japan, I studied Japanese" to mean you studied before going.
