School and well-meaning, 真面目 people with an overactive sense of duty will teach you Type 3.
Your normal, sane friends will teach you Type 4 for a laugh at your expense 😛 .
When you ask questions, people will answer with Type 2.
Type 1 is the only real kind. It’s the only kind you need to know. But even if you ask for it nicely, people won’t give it to you. Because either they don’t know where it is (unconscious competence), or they don’t think it’s right for anyone, from any country, to use it. So you take it. You take Type 1 Japanese. You steal it by observation and imitation.
