at athens internatinal airport

At Athens international airport, I saw a group of high school students near one of departing gates, maybe, coming from U.K. Two male teachers in their middle-age accompanied them, and managed and led this total of about 30 boys-and-girls all together.

These students were literally so different.
An obliging girl with dark brown hair was giving a shoulder-massage to the boy with short curly blond, who were sitting before her and closed his eyes with fully relaxing. Then, they switched their roles.
A little bit fat boy was carrying a ukulele and found an empty seat in the middle of boys-group.
There was one class-mate-couple, and the girl leaned on the boy who was the only student having a thin mustache.
Two fashionable, bad-guy-like boys were having sandwiches at the cafe, and besides them, a teacher in short pants talked with them with laughing each other.
A little bit fat girl accidentally kicked her friend's baggage while walking through the students, and said "wow" comically, two times, instead of saying "sorry". The girl, whose baggage was kicked, also kicked this fat girl's butt in reprisal. The boy who sitting beside her laughed for a while.

Seeing these, I just wondered if we, my colleagues and I in our office, are also so different and have so various characters like these students.
Maybe not. In our company, we all may seem to be same, because we are all in business suit, because we are doing same business, which we chose for living.

Here was Athens international airport. For a while, I remembered many of my high school class mates. We were so different at the time.
