Is Nellie a rabbit Mathos? Hair on her chest and can thump? Hmm... that's quite a puzzler.
(But anyway - now I definitely know Nellie's not based on me - no hair on my chest, I'm happy to say- that'd be quite an embarrassing problem for a woman to have to deal with..).
I don't understand the second stanza either. She screamed, "Give me the rest." The rest of what?
I do get the third stanza- the part about Mathos doing things he shouldn't oughta. I've been on to you for quite a while. It worries me that I find it amusing instead of just plain old despicable though.
I think you can do better than this Mathos. This doesn't rise to your level of talent and skill at all, really. Look back at your earlier efforts - the Tiger, the Bull. More advanced syntax and vocabulary in both of those Mathos. Don't try to hide your education Mathos- what's the use in that? You paid for it (with time if not money- formal or informal as it may be). Don't be ashamed to use it to its full advantage.
What a day. I got home and Pearl was hopping around like a little kangaroo just barking and growling up a storm and peering around the side of the house. I was almost afraid to go see what it was - I thought it might be some wild animal of some sort or something scary like that, so I just sort of peeked around while yelling at her- "What is the matter with you?" -and there was this guy all dressed in camouflage with this hat on that had a wooden spoon pushed through the brim about two feet from my face. I almost jumped a mile. He advanced really slowly, Pearl was putting on a scary show of things - and said, "I just wondered if you could fill up my water bottle?" I said sure - he had two water bottles strapped to his each side of his belt.
I asked him if he needed anything else and he said, "No, just hiking through." Then I apologized for Pearl being so unwelcoming and he smiled and walked into the woods. Maybe you could write a poem about that. Pretty interesting and unique character. At least in my book.
