My umbrella

One day it was raining. On the way to the school, I left my umbrella in a train. So I bought new one at the convenience store.

I said to the AET (Assistant English Teacher, whose name is Bond),
"I left my umbrella in a train."
Bond replyed "Me too.", with some actions.

After school, I had to go to the post office. It was still raining.
I looked for my new umbrella that I bought in the morning.
But I could not find it! Someone might stole it.
Then I went to the post office with other ombrella.
After that, I returnd to the school.

I said to Bond, "Someone stole my unbrella! New umbrella."

などと、その先生と話をした。簡単な会話はどんどん話しかけるのがいいかな。
