Too much TV?

Today I told Xan thank you for helping me and he said "it was my pleasure!" Then later I put his stool up to the counter so he could see what I was doing, and he said "That's too close for comfort!" and he moved it away a little. When I asked him where he learned those phrases, he gave me his usual answer anytime I ask him where he learns things. He said "I learned it from school that's by the Daybreak gym, but we haven't learned about airplanes yet."
