In a one day morning, when you walk to bus the bus stop, I saw scene like this picture. Then I felt nostalgic. I use to go to the school with my friends who lives in same area when I was a child. So, I could talk anything such as what did you watch the TV last night? or what did you play with your friends? on one's way to school.
I think this system is good for children. If you in this case, you have to fit in with others! I had to walk at the same pace as my friends. It was sometimes difficult for me, but I could learn the basics of a group action. This scene bring back memories!!
