I love the sarcasm in this Melissa - It cuts as well as the "sharp tongue" And your use of language is first rate!

Are you comparing Mr Pain Causer to a dog? Ha ha...I come up with freaky interpretations..loved it, specially the how painful, end...

Wow, this piece is amazing, truly excellently written. I can deeply relate to it. Whole poem contains great atmosphere and every stanza is very effective, filled with emotions.
My favorite part is:

-Hey there best friend
could you possibly wag your sharp tongue
just a little to the left,
I don't think you've mangled my heart enough-

at least not yet-

The line -at least not yet- adds great effect to the atmosphere and the flow of whole piece.

5/5 from me
