Harper Lee Tin Cans Quotations

I remember when my daddy gave me that gun. He told me that I should never point it at anything in the house; and that he'd rather I'd shoot at tin cans in the backyard. But he said that sooner or later he supposed the temptation to go after birds would be too much, and that I could shoot all the blue jays I wanted - if I could hit 'em; but to remember it was a sin to kill a mockingbird.
