During my highschool exchange program in Thailand, I stayed in a thai host family. My host mom was a teacher at the highschool I attended. One day, she asked me to help her with some work she had to do: checking exams. It was a multiple choice exam, so the language was not a problem. I said, sure, I'll help.
The next minute I'm sitting at the table with a pile of exams to check, and my host mom is watching TV! I was confused: didn't she ask me to help her? Doesn't 'helping' mean that the person who needs help participates? Apparently, she had a different philosophy.
