The yesterday's "photographer" is...

...Ketherine. I told Christina - the only coordinator of orientation - what had happened yesterday, and she explained that they're surveying each homestay if their students were living in good condition. As there're hundreds of students at the Language Institute and certainly she couldn't do that just by herself, she'd asked someone else to help her doing this job. Besides Kethirine, also Carol and Rosamund are helping doing the servey. Hmmm...it's good of them to make records of their students. Yet I still hope they can inform their students previously; it is their private after all. ...Eh? Their could be a chance that they have informed the Turners, but the Turners had forgotten to told me...
