The sun was too harsh on this day when I took these photos which could explain why these vines have dwindled. It's not clear to me why plants react in this way whenever there is something that is not favorable to them. A few hours later, these vines have invigorated after the sunset.
Is it their way to cope up with the stress that the harsh sunlight has brought on them? Or is it a very quick hibernation? That's a crazy assumption to make or maybe not.
Anyway, here are the photos from my walk during that day.
