Started ex006. This is all my own code, no peeking at the solution you provided and all within 30 minutes of coding. I know it's 15 minutes over but I was trying to get to to work.

The program is left is a continuous loop and I need to figure out why it's doing that..
Also -- i can see why you think it's 2 socks at a time, because that's one natural way to grab socks in real life -- but for the purposes of this problem, it's supposed to be 1 sock at a time, until you get a matching pair (i.e., among all the socks you've pulled so far, you can find one matching pair somewhere in there--)

I.e., just `#pop` not `#pop(2)`
