They say you can choose your friends but not your family. The same goes for mothers-in-law.
But one brave husband has put his relationship on the line to hit back at his nosy mother-in-law.
According to the man, his wife's mother has an annoying habit of going through her phone.
So he decided to take matters into his own hands.
"Her mother is generally very nice and tends to have a great attitude and be very enjoyable, a bit of a prude but generally enjoyable," he started in his Reddit post.
"However [she] can be a bit of a major snoop. If my wife leaves her phone sitting around she will just pick it up and start going through it.
"My wife has kind of laughed this off as a remnant of her mom being controlling when she was a kid.
"I'm not a fan of this because my wife and I will sometimes text about thing that simply don't involve her mother and I don't feel are her business at all.
"So over Christmas I saw my wife set her phone down on the kitchen counter and I had a brilliant idea," he continues.
"Her mom was still in the kitchen and I sent my wife the most sexually depraved text about all the things I was going to do to her when everyone left. [Honestly most of them are things we haven't even done, but I had to make it extra scarring ...]
"I sent this text from the bathroom. And maybe it was my imagination but I could swear I could hear an audible gasp shortly after her phone went off."
Moments later it became clear his mother-in-law had read the text.
Awkwardness set in.
"When I went out her mother absolutely would not look me in the eye. Then not-so-discreetly asked her daughter to come talk to her in the other room.
"When my wife came back into the living room I thought she had been crying, however upon closer inspection she was laughing.
"Her mother had questioned her about me, and if I always talk down to her like that.
"My wife had told her kindly that what we do is between us and us only.
"Probably the best gift this Christmas."
