Influence of the typhoon

Oh my god!
My friend could not go to Thailand by influence of the typhoon today.
He has only a short vacation.
But he was able to change departure.
So he can go to there tomorrow.

The typhoon also gives a damage to economy.
I have never thought it.
I understand a damage with the head.
But I don't experience it.
It's reason.

My friend experienced.
So I understood a damage with the head.
