The reason I started note

Recently, two travel plans were made.
One is a family trip to Hawaii, the other is more precisely a parent-child study abroad trip to New Zealand.

I was good at English in high school.
But it was long time ago. I forgot many words or idioms. And I didn't speak English like native.
So I am starting to worry. Specialy about a study abroad trip.

I need to study English. But I don't have any time to go to English school. 
So I started to write here.
It's hard to read, maybe.  I will make many mistakes. Sorry about that.

I will do my best!
