During the class, I visited the website of Yahoo! UK to send my homework to my teacher. Had I hardly click "Mail" when a big picture of a girl in swimsuit displayed on the screen. But, I had to keep the screen on until I finish inputting my e-mail address and password to register in the form next to the picture.
When I finished inputting my e-mail address, my teacher said "He*1 is watching something sexual.". Then, everyone there watched my screen and scorned me. I excused myself for watching the picture by saying I just wanted to register.
I wish yahoo! UK refrained from inserting such a misleading picture.
*1:Means me.
