Hi, wolfrainvn, I think your description is far much better than mine.

BTW,
It is not a matter of English language practice, but I found one big difference.
You thought the child in the left was a girl, while I thought he was a boy.

I first thought that it might be his first-love to his teacher, because he didn't see the computer screen, but stared at her.
But I denied the thought myself, because another child (girl) too was staring at her...

Now when I look at the child again, I can't identify his/her gender.

Anyway, thank you for your description. I've learnt a lot from you.
I will be much appreciated, if you provide me your description from now on, if it is allowed.
