Beards

T: "Mom, you know Jen?" (my sister)
Me: "Yah."
T: "Did you go inside her house?"
Me: "Yes."
T: "Did you go to Disneyland?"
Me: "No, but we did go to an aquarium and whale watching in the ocean."
T: "Is Jen a whale expert?"
Me: "Kind of."
T: "I have a friend named Hant who thinks he is an expert but isn't really an expert on whales."
Me: "How do you know he isn't an expert?"
T: "He doesn't have a beard. If you don't have a beard, you're not an expert on whales."
Me: "That's funny, son."
T: "No it isn't."
