The most important thing when you’re looking for a language parent to help you speak their language is for you to change your language.
What do I mean?
Take words like
teach, study, teacher, learn, class, tutor
completely out of what you say to someone you’re talking to.
Use words like
friend, help, play games, speak, understand
instead.
Why?
When you say “teach” people immediately think “teacher.” That’s a title that’s earned in a lot of societies, and it’s likely the person you’re talking to won’t have it. It’s also likely better if they don’t. Read why here.
