英語わからない

Not that much of a post, but I want to register this. 

Today I had to use a bus, and when I was asking how much it was, the driver answered to me in english.

"two, twenty"

and I kinda blocked because I really couldn't understand what the guy was saying. I guess my head was set with the japanese language mode (I really only use portuguese and english online)

"two twenty". 

And I was like "はい？".

"two twenty" 

Until it hit me, "にひゃくにじゅう円のことですか。あ、わかりました。はい。"
