 Why doesn’t Eddie act excited about Teena going prospecting with him?
Eddie Taylor would like to have finished it, but the bar of morning sunlight poking in under the window shade pried his eyes open. But, from what I hear, there are plenty of rock formations. Still, one clue is as good as another when it comes to hunting uranium ore, I guess. In fact, anything having to do with atomic science excited him. You couldn’t have a father who was head of the atomic-science department at Oceanview College without picking up a little knowledge along the way. When carefully controlled, the radiation stored up in such isotopes was used in many beneficial ways. His father usually volunteered any information he wanted known, so Eddie stuck to questions which could and would be answered. It took Eddie over an hour to sort out the newspapers and magazines in the garage, tie them in neat bundles, and place them out on the front curb for the Goodwill pickup. The best way to get there was by rowboat across Moon Bay, and that was too long a row to be starting now. Besides, there were plenty of other places around the outskirts of Oceanview where likely looking rock formations invited search with a Geiger counter. The taffy-colored cocker spaniel yipped wildly over his freedom, racing back and forth as Eddie started down the street. 19 Christina Ross—whom everybody called Teena—lived at the far end of the block.
 Eddie has a crush on Teena, and therefore doesn’t want to act too eager and uncool.
 Eddie doesn’t want Teena to come because there isn’t much time left in the day for prospecting Cedar Point.  Eddie has a crush on Teena, and therefore doesn’t want to act too eager and uncool.  Eddie doesn’t want Teena to feel like she is obligated to help him fulfill his dream of finding radioactivity at Cedar Point.  It is implied that Eddie doesn’t want Teena to feel like he knows a lot more science than she does. Eddie feels this will make Teena not like him.
