We can’t figure out whether this is evil, genius, or both?

In-laws aren’t always the easiest people to get along with it and one man in particular had had enough of his!

He posted on reddit saying that he had lost it with his “insufferable” in-laws and had come up with a way to keep them away from his house.

He wrote:

I have insufferable in laws. Father in law is manageable, but mother in law is crazy. 

My wife’s parents are really traditional. Privacy means nothing to them, and my wife refuses to set boundaries.

They will come around every day unannounced to visit my wife/play with our kids. So not only do I never get a break from my mother in laws constant nagging, I have no privacy from them.

Wife has ignored my concerns for years. My mother in law is arachnophobic. A few months ago she went crazy after a (wolf?) spider was simply in the corner doing nothing. Panic attack and all.

So I got the idea to get a tarantula as a way to prevent her coming so often. It’s in a big enclosure in the living room. Asked wife before hand if it’s okay, but didn’t tell her the motivation.

Worked like a charm, the dad still comes but the mother can’t stand to be in the same house as it. I’m mainly asking if AITA as I wasn’t upfront with my wife. But she’s continued to ignore my concerns about boundaries for years, I don’t think I had a choice. Plus the tarantula makes a cool pet.”

Genius? Or a step too far?
