2. He’s Mean to His Mother
It’s one thing when girls cat fight with their moms. I certainly do it all the time. But mothers and sons have a different bond, namely, they all believe that the bearing of their son was the second coming of the Messiah, and treat them accordingly. If a guy cannot appreciate this woman who will certainly kiss his ass more than you ever will (since you KNOW when he’s being a dumbass, while she either ignores, or refuses to believe it), it proves that no matter how nice he seems to be to you now, at his core, he’s a mean, ungrateful person, and the kind of treatment he gives to Mommy dearest is what you have to look forward to. Not to mention, the likelihood of “If you ever speak to your mother like that again, I’ll make you wish you couldn’t speak” speeches to your own little Messiah is slim.
