The only thing amusing in the article is how Americans are amused by this.
I remember on my first day to school my mom took me there, but she didn't come to take me home. I was one of the few kids that cried because my mom wasn't there. Later, I felt embarrassed by that.
Our school organized some kind of a school trip about once or twice a year. I was the odd kid whose parents would not let him go on the trip. For everyone else, it was a natural part of school that they looked forward to.
Needless to say, the parents do no join the kids for the trip.
