I tried but what for?

I really did try
to strengthen the defense
to weaken the weakness

I really did try
to toughen my fences
even lit up the hedges

I really did try
to thicken the lines
make it better defined

But all that
for building my defense
All gone for a split second.

For I have built that facade
Little did I know
you'll emerge from inside

And so it crumbles from within
Walls fall like a messy
soft cake; failed

And now, from the very core you begin
I can do nothing
but let it be.
