这是我最熟悉的字～～

when i am here,i can meet a goodhearted people,i even call the goodhearted people"teacher",the "teacher" teach me how can right speaking english.It's rather pity to meet short-term.for example,when the "teacher" say 11:30pm,but there's 2:36pm in my city. Although I can't find him(her)here,i want to say"It's nice to meet you."
