Under the Bus

Wrote this some time last year , probably influenced by some life circumstances at the time.
Will continue with "Chronicles of Alan" as soon as I am Done with the Kitchen I need to finish ! ( currently empty room with a Fridge and a sink, and a lot of boxes.)
Would appreciate your comments on :-

What do you think influences a person to write these sort of feelings/words down?

Met you by the dumpster, been beaten
Playing in a card game caught cheating
Came across like the good Boy Scout
Face like yours I wanted to help you out

You never ever told me where you came from
The places that you mention don't exist
There's about to be a hell of a big explosion ( Chorus)
Or are you gonna blow me off with a kiss

Who is that Guy looks like he knows you
The way he stares at me have no value
No humanity exists behind those eyes
Say you don't know him are those lies?

You threw me out and under the Bus
Was it just you or was it the two of us?
Always looking back, what could you see,
Was I an embarrassment, was it me?
