Intelligent Grapevine?

This is almost scary. You've heard the whole "no straight lines in nature" bit. There's a potted plant here on our deck about 3 or 4 feet from the wild grape vine. And darned if this picture doesn't show that it is specifically reaching for the plant. It hasn't actually REACHED the plant yet, there's about an inch to spare. But there's no droop in that branch. It has a purpose. It knows it's there.

How????
