Am I the only one that's not mad about my crazy mother in law? Lol

The other day I was chatting on Facebook with my mother in law (whom has always been rude and outspoken) and the conversation went as follows:
Her: "what are you naming my granddaughter again? *inster name*...and what was that weird middle name again?"
Me: "yes, *insert name*. And that weird middle name you're referring to is *insert name* which your son picked and loves. 
Her: "hmm. Well at least I can know that I gave my children normal names." And just so you know I will be calling her Anna because I love that name... 
Me: "Anna? That's not even part of the name were choosing lol! And if you do your son will have a fit"
Her: "well I will do it behind his back then."
For some reason I am finding this absolutely hilarious and laugh about it multiple times a day. I know I should be furious but for some reason I can't be mad and just find it so entertaining! What is wrong with me. Lol
