Drunk Daddy

Ethan showed me one of his toy teacups and asked, "Hey Mom, is this wine?"
Josh and I don't drink wine, so wondering where he even heard of it, I said, "Wine? What's wine?"
Matter of factly he stated, "It's what you drink when you get drunk."
What!? How does he even know what drunk is? Staying calm, I asked, "Who do you know that drinks wine?"
"Dad."
"I don't think Dad drinks wine."
"Yes he does."
"When?"
"When he gets drunk?"
Josh claims he's innocent!
