When your smile turns to a frown.
We used to glance at each other with such hope. Hoping someone would act first.  Now I glance at you hoping to meet that glance one more time so I know I should act. Now, I look away quickly just hoping you don't see the crying hidden behind the fake smiles I use to walk down the hall.
When your smile turned to a frown I realized I was just a fill between her and the next.  I realized you never liked me at all.  And I realized I fall too hard too fast.
When your smile "comes" to me again...this time I know to walk the other way.
