Three words

I wrote three words
Keep them with me
Hidden from you
Escaping with scars
Heal from my spit
A cut from the edge
I forget a promise
I keep my word
I forgive a mistake

Cleaning the wardrobe
Encase some things
Should I throw them away?

Its all right, it's over
I feel fine
A little empty inside

And never relive
Any secret lie
Any evil withdraw
But these words
The secret thoughts
I'll never give you

All for your sake
Withholding the end
A number to call

I would like to say
The three words
I don't know how
