I am in the Middle of Them

I am in the middle of them
I think I am like nothing
They are superior
Unlike me, inferior

What do you understand by superior?
How about inferior?
Indeed you never know
For they are terms of mine

When I am in the middle of them
I feel embarrassed
When I am in the middle of them
I feel useless

I admire them so much
I adore them
more than you know

What do they actually think of me?
Do they think that I am nothing?
Do they consider me as the one who is useful for them?

They are sometimes arrogant
When that sort of thing appears, my admiration is gone

They are sometimes kind as well
When it appears, my adorableness is getting higher

They..
Do you know who they are?
