Another application text

OK, I've finally written a text about the last question of my application form for my NZ homestay programme.
Question: "What do you feel you can contribute to your host familiy's homestay experience?"
My text:

I know that taking part in a homestay programm as the host is always linked with some work or strain. At least you are offering your free time. That's why I am of course willing to contribute something to my host family's homestay experience:
Perhaps they are interested in my hobbies or interests- I would love to share some of the things I know.
I imagine that life in Europe is different to life in NZ... since they are showing me their way of life and living, I can also show them mine (if they want to!)
And I don't mind to help for example in the household, as they are helping me, too, by taking me as a "guest".

Does it make sense? I'm still looking for some kind of "links" between the single aspects.

Thanks!
