Language 101

So, I've been learning the language for about 2 1/2 weeks now. Some days my mind is fried, as my friends here can account for the loopy behavior I attain post-classtime. The other day, my teacher and I were sitting in McDonalds and she was reading over my homework. I was supposed to select the proper sentence to match the picture, and form a paragraph with all the sentences. Well, I didn't really know any of the words and lets just say instead of Mei Mei being a good friend and a hard worker - she always steals other people's books and nobody likes her. Yep - I picked the wrong sentences, but my teacher laughed so hard she started to cry. At least the paragraph made sense? :)
