Really??? What would you like to learn?
you know, in the old days in asia, actually it still is, that when a person comes to your school and said "please teach me your stuffs", it's a subtle way of challenging. it's one of those passive-aggressive thing. we asian are very polite about stuffs. one minute, very polite, and the next minute, your hot dog disappeared along with slaw, onion, ketchup and other stuffs.
