A prune imminent?

       For at least two, or three reasons.
1.  If you haven't followed it from "Day 1" it started off looking like the Extra in this post.. 
2. It's hanging some of it's branches rather low.
3. As seen in the little inset; every time there's a lowering it puts out roots, "hoping" for somewhere to root and proliferate.
Actually - 4. There is a rather obvioous "Main" Trunk - NOT sure the photo shows it well enough.
