Today was an language exchange day.
My language partner is Risa.
I was introduced her by my good friend.
I registerd in SNS and updated my profile.
But I received only 2 response.
Even though I reterned one person, no contact since then.
An another person doesn't give me some enough information, so I don't know his or her age and gender.
I think it is difficult to find some language exchange partner on SNS...
So I might be introduced someone by Risa.
It is the most safe and trust.
