When you’re in the park with your kid, and a nice lady with a dog is chatting you up on the park bench, and your son is staring at the dog’s hind legs, and he asks,
“What is that black thing coming out of him?”
And you take a breath and answer, “his balls.”
“And what’s that long white thing?”
Your eyes darting from the lovely Hebrew-speaking lady to your son.
“It’s his penis.”
“A dog has balls and a penis?”
“Yes, just like you.”
And with that, 4-year-old mind blown.
