Favorite

Out of the three of you, you're my favorite

Still had two other friends, so I was her third overall.

I had never been anyone's "favorite" always "one" of their best friends 

One situation I was a favorite, but it was only temporary, she had met better me's in class.

But being third favorite was the closest I've ever gotten to it, I really appreciated it.

But then, I felt it.

When you're a "favorite" anything you do could make them change you out for someone else.

Feel no emotions, have no opinions, have only time for them

Always be on their side, don't think about yourself or others. 

Don't have time for yourself, think only as them.

To be a favorite, I have to mantain myself in the way they deemed good enough

for third place.

To never grow, to never think, to never speak, like talking to a wall

until they inevitably get bored of you, and you go back to just being another friend.
