Eyes are everywhere.

I've seen generations in my life time,many young families growing
old.
Ive seen happiness, sadness and joy.
I've seen those arguments you think know one has heard, i've heard
secrets but never told them.
I've been many colours, bits stuck onto me, i'd like to scream no "no
fly posting" here!
But i'm just a pile of rubble waiting to be cleaned up now,you knocked
me down!
After all i was just a wall in your house.
