The true lesson is people with ADHD shouldn't have a collection of rocks based on the alphabet. So what if Z is missing. It looked nothing like a Z. Get over it. Maybe it is actually somewhere around here though. I'm tired now. Yo, where's the Z shaped rock? Now I'm extremely tired. Finally. But that rock? Oh well. Zzzzzz

Where's that freaking Z shaped rock!?!? Let's build a new one!!!!
