Yesterday, when I was walking in the street, I met an old friend of mine, Li Na.We haven’t seen each other for a long time. It seems that she has changed a lot. I am very surprised.She used to wear short black hair. But now she has beautiful long curly brown hair. She used to be a little heavy and quiet. But now she’s very slim and outgoing. She used to be terrified of dogs, but now she even keeps a big dog as a pet.We talked a lot, and we both missed the old days.
