Because they're likely to influence you more than anyone e{#blank#}2{#/blank#} you have met and will meet. So if your dad worships a football team, s{#blank#}3{#/blank#} as Pittsburgh Steelers and Atlauta Falcons, you are likely to grow up being a big fan of a football team. And if your mom loves to r{#blank#}4{#/blank#} , you might grow up just carrying a book wherever you go, just a{#blank#}5{#/blank#}she does.
But parents do a lot more than just pass along their h{#blank#}6{#/blank#} . Moms and Dads need to care for their kids from the m{#blank#}7{#/blank#}they're born. It's parents' task to love and guide kids---and most parents will do this as l{#blank#}8{#/blank#} as they live----even when the "kids" have g{#blank#}9{#/blank#}up and have children of their o{#blank#}10{#/blank#} . That means you have many years ahead to share with your mom and dad.
