Class Observation

Today, I went to Language in its social context class.
I met Lauren there, so I became happy!
But when the class start, changed my mind, because student spoke so fast. It's difficult for me.So I almost couldn't understand.
They're sometime laughing for joking, but I could'nt understand, so I'm feel tired.
But to have went to the class was good experience for me.
Students have own opinion, they answering question as soon as possible, and they were enjoyed their class I think.
It was different to Japanese class, so I decided I'll try to participate class positively!
