Kay talk

Kay was playing with a little toy giraffe that we have and she asked me, "Are giraffes from the zoo?"
Me:  "No they live in Africa."
Kay:  "Oh, what's Africa?"
Me:  "It's a continent."
Kay:  "Oh, how do you know that?"

M&M and I were laughing at that conversation and Kay was confused as to why we were laughing so she asked, "Is my joke funny?"  We answered that she was funny.  She then said, "Oh, sorry (laughs)."
