How time flies! It's been a year since a day I said goodbye to my British friend，Toby. Yesterday，I received a present from him，and memories of him came flooded back. I first saw him in front of our classroom in the first day of school two years ago. He was an exchange student who would study at his school for one year. I was deep impressed the moment I saw him，since he seemed so much humorous and outgoing. During his first few month，I helped him by offering my advice and explaining some difficult Chinese. We often hang out together at weekends，that was a good chance for us to share our cultures. I wish meet him again someday.
