A few minutes later we had the following conversation:
Squink: "I heard a bad word, mama".
Me: "You did? On the radio?"
Squink: " I heard a shhhhhhhhhhhhhhhhh"
Me: "Oh?" (feeling a bit busted)
Squink: "then I heard an it"
Me; "Oh?" (feeling even more busted)
Squink: "And it sounded like it came from you mommy, even though your lips did not move"
