Ok, so maybe I exaggerate when I say monster. Maybe it's really just a mouse. (I get that if there's "A" mouse, there's more than likely mice plural, but it's easier for me to pretend it's a single, solitary one that is terrrorizing me. It's a little more tolerable.) To ME, though it's a monstrous problem.
I'm not a fan of mice. Not even a little bit. If you look in my pantry, it is practically bare... every food item NOT in a glass jar or metal can is in my fridge or freezer. I want the mouse to die and never, ever return again (like as a ghost to haunt me... it's friends aren't welcome either). I would probably be like the little old lady in the movie Ratatouille and actually shoot at it if I owned a gun. I'm that irrational when it comes to this unwelcome, uninvited intruder.
My young sons get that I'm completely horrified by the monster in our house. We had a little teaching moment the other day (Chase teaching. Me... listening, but not really open-minded about the subject matter!)

Chase: "Mom, didn't Heavenly Father create mice?"
Me: "Yes, He did."
Chase: "Why do you want to kill Heavenly Father's creations?"
Me: "Well, Chase, I don't know what Heavenly Father's intentions were for mice, but I'm sure they are not meant to inhabit humans homes and get into their stuff and poop and pee in their pantrys. So, since that's what is happening, I think it's ok for us to get rid of the mice in our house."
Chase: "Well, maybe Heavenly Father just made a mistake."
Ha, ha... or maybe I need to be a better example. I just don't see it happening. Not anytime soon. Just not when it involves His creation, the mouse... in my house.
P.S. There's a super cute kids song called "there's a monster in my house"... it turns out to be a snoring father, but for me, well, you know what my monster is.
