I like the Montana/apple story.
A friend gave our two kids used bikes after they came home. They both said, "Gracias" to which my friend said, "dinero". I said, Gina, now they think you are asking them to pay for the bikes, the response is, "de nada".
The kids use to ask my husband to say Spanish words and he would try, usually his pronounciation wasn't
that far off and then they would laugh hysterically and repeat how he said it. Cheap entertainment.
