Hip.

I can tell you exactly the moment Ian became hipper than me.  It was at 4:35pm on Tuesday, May 24, 2016. 

We were chatting about school and I asked him a question.  Ian used "IDK" as a reply. 

Yep, there ya go.  The scales for "hipness" just tipped in Ian's favor. 

Fortunately I recovered quickly and kept the conversation moving along.  All the while I'm thinking, dear G-d, I was able to navigate this without looking foolish questioning what it meant, but what will happen the next time?????

**For those who are wondering what 'IDK' stands for, it is I don't know.   Now, I'm not saying I don't know what it stands for, I am saying that it is "I don't know."   :)
