Astronauts, etc - Shake It Loose

Get inside, into my house 
I know that you’ve plenty left to figure out 
But I am sure 

Hesitation at the door 
Don’t leave me with reservations on the floor 
I need much more 

Listen to my careful words 
See through them, and signal to me that you heard 
What I can’t say 

Tangled up inside my head 
I need to shake it loose, try to forget 
Why you’re away
