This three weeks stay is lovely.
The room is cozy. Everything is good. Public transportation is also convenient.
I had so many good experience with John.
I visited John"s school in Oakland and taught the kids how to behave like Chinese students.
John took me to a pet store. We bought two pet rats home.
He drove me to Bart station 4 oclcok in the morning. Isn't he sweet?

Thanks John. Hope to see you again!!
