Agreed. And you should break the ice, beggining with the greetings perhaps, then taking advantage of the surrounding setting. Perhaps your clothes, you could ask where they bought, if they haggled to get a lower price (or not), about the patterns, collors (that they and you like or not); without being overbearing or judgemental. Just out of curiosity.
Let them at ease, perhaps they have a joke that can be brought up to the table or something like that.
You can talk about your backgrounds, your origins, where you came from and what are your plans, about artists, music, food, learning, hobbies, places, yada yada yada...
Well, it´s something already, ain´t it?
Don´t let them "pick up the slack of teaching" by themselves, you have to work togheter with them, somehow. The very fact of offering to help you out, is already a good thing, don´t blow that opportunity! Good luck on your studies.
