4 days

I'm back home, and in 4 days I'll leave again. I'm very excited, but also very sad because I won't see my family and friends for such a long time.

What will change while I'm gone? I don't know. Probably that's what fears me. But I fought so hard for this exchange, I surely won't give up and stay at home.

What will change?
The answer my friend is blowin' in the wind, the answer is blowin' in the wind.

I got this great chance, and I will take it.
