You want more but don't know what that is

They sit across from each other and wait for their food
About an hour prior they were having intense sex
The sweat was running off their bodies
He knows what she loves
She knows what he loves
It was a mutual need, nothing more
Now they sit & talk about nothing
They both know that they're looking for something
Each know the other isn't it
Yet they go on talking & fucking
Idly
Watching out, not to get too deep
Neither has the energy
They couldn't if they wanted to
Both know the other isn't concerned too much
In the meantime they're looking
That was me tonight
I don't know what I'm looking for
In someone else's eyes
I don't know if I'd know at this point
You can get so numb over the years
You'll work, pay taxes & lie to yourself
The whole nine yards to nowhere
My eyes drifted off to the street
The lights of the cars kicked at the corners of my eyes
I forgot to pretend to listen
I was filled with emptiness
I felt old & stupid
I could do nothing but breathe
Now I sit in my room alone and I feel better
Sometimes you're faking it
Sometimes you're a coward
Sometimes you just get tired of taking the beating
