Now What Do I DO?

The cat tree I ordered came. When R and I took a long walk this beautiful afternoon, after I had been to yoga and shopping for everyone else but myself (it was still fun), we returned and found an enormous box blocking the doorway. I couldn't lift it, but turned it end on end till I got it to the now-empty room, where it will go. When I opened the box, there were the pieces, and I realized that I am awful at putting things together and have NO CLUE how to do it, though I am sure it is very simple. I will have to wait till R deigns to assist me, or ask Jeremy to come over and help. That's the likelier scenario, as he loves the cats, and R doesn't.
