this girl. seventeen.

So my youngest daughter turned seventeen yesterday.
Seventeen.  MORE than one and half decades. A daughter of  10 + 7.   Years.
How does that happen? Life happens. Before your eyes.  Looking. Not looking.  
The child you brought into this world transpires.  The years ensue.  Hastens without control.
 And you see before you your almost adult child. And this in itself is a collocation.  
Forever your baby.  All of seventeen.
