What’s the dumbest argument you’ve ever had?

Last night, my husband and I literally got in an argument because he wanted a milkshake… and I told him I couldn’t make any because I didn’t have milk… or even that much ice cream. He LITERALLY TOLD ME… “you melt the ice cream, and you have milk…” no mind you have sugary melted ice cream. Not milk. 🤦🏻‍♀️🤣 ice cream uses more than milk… but sweetened cream, too. Am I right? But he wanted to argue with me that we didn’t need milk to make a milkshake. 🤦🏻‍♀️ it’s like saying you don’t need ice to make a slushee.. that’s, like… THE MAIN INGREDIENT! And of course, it boiled down to ME being a “know it all.” 🤦🏻‍♀️ what’s the dumbest thing you and your SO have argued about??
