une japonaise?

An interesting class, Creating a Retail Store Image.
Each of us is building a creative proposal of a store within 12 weeks.
The best part: Money is no object!
I've heard this phrase so many times at this school.
It's kinda nice... somewhat let all the students be as creative or as crazy as one wants to be.

Anyway, during the break a Japanese lady came up to me.
She started speaking Japanese to me.
So, I told her I wasn't Japanese but I did study it before.
She asked me to help translate the homework and stuff which was doable.

I asked her, how did she know I speak the language.
I hadn't spoken to anybody since it was the first day and I sat right in the middle of non-Asian.
She said I looked like one or at least a half-breed.
Hmm.. I'm a half-breed but no Japanese blood.
