For most of electronic appliances and software, I just can use properly it if it’s not in English. Especially Indonesian interfaces (and manuals) – I usually change the language to (or use) English or translate the terms to English to be able to properly understand what it mean. Mind you – Indonesian is my native language.
It’s mostly thanks to the fact that ever since the first time I ever use an electronic appliances, they’re all in English. It’s just recently (by recently I actually mean 10 years or something) that Indonesian started to be available in them. And as the effect, I understand the English terms better than the Indonesian counterpart.
How about you? Do you prefer to use English instead of your native language for anything?
