As the summer vacation are coming soon, my classmates are
trying very hard to get train tickets to go to home. But
I have made up my minds to spend the vacation far from
home for first time in my life. My parents have agreed
to visiting me, and I will have a different vacation. When
they came here, I will show them around my university
and the city as well. I have decided to buy it
some nice gifts. It will be a big surprising for them. My
parents have done a lot for me, and I think it was high time
that I did anything special to express my thanks.
