The Difference between Big & Large

Big: Except descrbing something huge than average size, it also means large in degree, or something important / major.  For instance: "You two are in big trouble." "You took a big chance."

Large: Different from big, large is mostly descrbing soemthing bigger than usual in number and amount. When we emphasize the "quantity" of  things, we would use the word "large."  For instance: "Young kids carry the large amount of crack."

Nothing Special about Lily~

It is always embarrassing for me to do the self-introduction each time because I am actually a boring person with nothing special to share with others. However, this might be the last time for me to do the self-introduction in school; I will try my best to do it in an interesting way.
