Twists and Turns

I found something on one branch of the tree. I found a small twig-like branch twisted around a slightly thicker one. The only part that confuses me is that the small twig branch (it's practically a stick that can curve, I guess) is disconnected from the tree. How did that happen? The twig part of the tree, not from a different tree, I checked. Anyway, I'm going to personify this a bit in a way that might look like it's a real life situation: It's almost as if the twig isn't ready to let go yet (is that simple enough?). How did you guys feel when you had to leave middle school? What do you guys(kids who are still in highschool) think it will be like when it's time to leave highschool? Would you do the same thing the twig did-- hold on forever? That is how I see the twig as-- not ready to move on yet (believe me; I tried to pull the weak thing off, but if I pulled any harder, it wouldn't be in one peace anymore). We people are not the only ones who don't know when to let go (I'm sure there are people who do know). It's not a bad thing; it just shows that everyone gets a shot to prove that they don't give up easily and will fight for what they want.
