The word "ever"

Darby has a crazy, crazy reaction to the word "ever." As in "Darby we don't ever put our hands near the stove" or "don't ever throw toys at your brother" and on and on. When I say anything with the word "ever" in the sentence she gets really mad and yells "don't you say that to me, EVER!" It's pretty funny and today she started saying it to Trevor when he was playing with one of her notebooks . . ."Trevor, don't you ever play with this notebook, ever, EVER, do you understand?" What a little sponge, these kids pick up EVERYTHING!
