wrong number

Hi, everyone, this is Ziggy.
Today, I got a call in my office.
I said “Hello” in Japanese.
Next moment I found that the speaker was talking in English.
To my surprise, I never hesitated to talk to her.
After all, she dialed wrong number, so it was just a little bit chat.
However, I found my skill has no doubt been improved even the level is low.
It was a little bit interesting unexpected thing.
