I am not the first.
To some I am the second.
To others I am the third.
But I'm never the fourth.
I am the first.
I'm no help in "a way out."
But I'm first in these words: "I", "don't", "know".
I can't be left alone.
If I'm alone, I will offend someone.
You can't make peace if you cut me off.
But on the other hand, you might.
I was inspired by this riddle by Mello, so I wanna give him props.
