The cliche that apples don't fall far from the tree holds much truth.
Kids tend to imitate their parents. They do it when they're little. I remember when my son was barely two years old and I called him to come upstairs to bed. He prattled back past the pacifier in his mouth, "I'll come as soon as I finish my essay."
They do it as they grow up. My husband and I are extremely proud of our son these days. When he wants to show off how tough and macho he is becoming, he imitates his dad by putting hot sauce on his food.
