To Mikako,
Yes, I do have an experience that someone unexpected talk to me.
When I was in high school I was in the tennis club and one day we had a tournament, so we were heading to the game venue by train. I was with my friend but suddenly, a guy started talking to us. He was a stranger to us, so we were a bit scared but as we spoke, we eventually ended up discovering that we had a friend in common. It was really surprising, and I noticed how small this world was.
Questions to everyone
1) What kind of sports is everybody interested in?
2) What is your best way of spending your weekends or holidays?
I just wanted to know because we didn`t really have a chance to introduce ourselves and this media might be a good way to communicate when we don`t have IE classes.
