Conversation examples

Here are some examples of “IDK” in action:

Example 1

  • Friend 1: Do you have any plans for the weekend?

Here, Friend 2 shows that she doesn’t have any plans for the weekend. It’s not exactly certain what she will do and she’ll figure it out when the time comes.

Note: “IDK” can be used in all caps or in lower case. Either one is fine.
