Japanese Conversation

Japanese is quite easy to pick up, so long as you don't intend to do
anything with it. A few greetings, watching your honouraries, some
adjectives and a useful phrase or two and you could get by. This is
because it's colloquial and context sensitive. With few exceptions you
can safely assume the topic is that at hand. Just use an adjective
whenever it might apply and say "hai" consistently whenever someone
talks to you. No variety needed.
