You know when your kid says something bad and you find it hilarious and or agree but gotta pretend you're upset

I'm a lesbian and I have a wife. We got a call from the principal because a girl was making fun of our son for having two moms and referred to us as dykes and called him a faggot even though he's not gay. My son told her "My mamas paid to have me. Yours got stuck with you because they're anti-abortion, but I'm sure you make them question that belief everyday."

We sternly told him to never say that to someone and how mean it is. But secretly we were laughing. I can already hear some of the comments about how we shouldn't be happy he said that to her and we are terrible mothers. But as far as he knows we are upset. Between me and my wife. Little high five.
