You could say
That I beat your name
Into most of the day
Usually pointless thoughts
Or sometimes detailed ideas
That you make come alive
If only you were here
For longer than this trite of hope  

You could even say
How madly in love I've been
With the thought that my head
Creates for us to blend
Or maybe it's this insane trend
I've started, falling in love
With the friend
Who doesn't notice
Our mouths are too close
To speak truths
That we once wrote
