ワードアップ英会話 WORD UP ENGLISH CLASS | 日記 | Vocabulary: "(every) once in a while"

The expression "(every) once in a while" means occasionally, and is located between "sometimes" and "never" in terms of frequency:

100% always

         often

50%  sometimes

        occasionally // once in a while

0%   never


Some examples:

  Once in a while I meet my friends in the park and play frisbee.

  Even though Tokyo is crowded, I like to go there every once in a while.


Using "every" with "once in a while" is optional, and does not change the nuance or meaning. But in my opinion, it's usually more natural to include "every."

So, what are some things you only do every once in a while?
