why volunteer work?

I met a lot of people at volunteer work. i only applied for using language especially English.
there's 2 types of volunteer work.

1. Using specific skills - language, controlling software (Power point, edit program etc)
2. Using strength ( carry load, arrange seat etc)

I only apply for 1st type of volunteer work. it doesn't need any tiring work. the people who i met 1st type of volunteer work, usually have a experience living in other country while they studying or working whatever. they raised wealthy family and also have an experience of variety kind of activity. and they are so busy doing working of studying or other things. people always ask me how i studied English or if i have an experience to go abroad. absolutely i say i don't have any experience to go abroad. and i don't want to study abroad but i want to travel all around world.

they look at me very strangely. i think i'm very strange for them. i think my English is average level. i've seen a lot of people who speak English very fluently with clear accent. i'm trying to study English and experience variety culture meeting people who come other country. but i don't want to meet foreigner aim for studying English. i think it's rude to meet with getting certain benefit. though i hope to learn their cultural thought and sharing information from their experience, i don't want to learn speaking English talking. it will be bored each other, and at least they are exhausted building relationship better. anyway, i learn volunteer work during the vacation, people ask me why i do volunteer work without getting paid. i'll answer them i get better thing than getting paid. and it's good way to widen my view to see the world rationally.
