Ugh, last time I explain Trees to you heathens.

The next open part of a tree is always the left-most leaf. The next open left leaf would be in the third row under the kitting needles. So the Book is now a child of the Kitting because B comes before K.

So we have two Paths: Laptop->Knitting->Book, and Laptop->Violin. If anything else is added, it would be for the knitting’s second child and could rearrange the entire thing

Why Hussie would want to show/teach people about Data Structures is beyond me
