To leave is not as bad as it seems.

You can leave someone or something and it still be okay.

But it can also be not okay.

For an example,people also leave when they love someone. Or when they once loved someone.

This person here,now sitting and looking at nothing in particular,just thinking,is regretting this deeply. They are regretting that they left someone,but they needed to do this. They had to protect the one person they love.

So maybe to leave is both.

Leaving — both good,both bad.
