To this day, Kevin Hart still recalls the exact moment he learned this lifelong lesson{#blank#}1{#/blank#} he says came about one afternoon while he was under the care of his after-school babysitter,{#blank#}2{#/blank#} kind, grandmotherly woman named Miss Davis.

    {#blank#}3{#/blank#} (typical), Han helped Miss Davis with housework after school. One day, however, Han skipped the housework and joined some friends {#blank#}4{#/blank#} a “game” of throwing rocks at passing cars.

    As it went, one of the {#blank#}5{#/blank#} (stone) Hart threw broke a car window. On seeing this, Hart and his friends{#blank#}6{#/blank#} (flee) from the scene. The car stopped and the driver stepped out to find who did it. Eventually, his friends all pointed to Hart. “They threw me under the bus so fast!” he says.

News of the incident quickly made {#blank#}7{#/blank#} (it) way to Miss Davis.

    He spent the rest of the day in panic, fearing what {#blank#}8{#/blank#} (happen) when Davis told his mother.

    Yet, Miss Davis never told. Her act gave Hart an important lesson about trust. “You've got to give trust{#blank#}9{#/blank#} (get) trust,” he says. He was so{#blank#}10{#/blank#}(thank) that he never got into trouble as a teenager from then on, all because of Miss Davis.
