My daughter is honest, a little bit shy, 12 years old girl.
Now she is good at making friends, but was too shy to talk with anyone

when she was about 2-3 years old.

We visited my wife's parents in Hokkaido about ten years ago.
Just when we got on an airplane, she burst into crying and shouting with all her body.
She probably felt frightened of lots of faces of people on board.
From her point, all of a sudden, many unknown faces turned up in front of her.
She went on crying on board until she had fallen down because of exhaustion.
I thought anyone in a seat near by must have accused us of bringing her
into the cabin.
They seemed to be angry.
We were sorry about causing them so much noise.
