 As Sherry and her brother Mark walked home from school one day, they saw their good friend and neighbor, Mr. Wells, sitting on his front porch. They greeted him warmly, calling him Gramps, as they always did. Hi, Gramps. Well, howdy, Sherry. Hi, Gramps. Hi there, Mark. Fine day, isn't it? And what are you two up to now that school's done for the day? Homework, maybe?
