Words are /are not

Words are not an ointment
So don't think that
They stitch and heal
Your cuts and wounds
They do conceal.
    Words are not a poet's pet
     So don't think that
     They only speak
     The language of love,
     The words of pain.
Words are not a cloud set
So don't think that
They will rain
Through my pen
Whenever a heart breaks.
     Words are not lightweight
     So don't think that
     You'd understand
     Too many things that
     I haven't said.
Words are not a floweret
So don't think that
They catch your attention
If you fall for them
Words are magic potion!
