The thunder was a second or so after each flash of lightning . Brian said , " Why do n't we pack up and head to my house to finish lunch ? " I ran , carrying my back pack , someone else 's backpack , a bag with the bread in it , and a crate of other food supplies past the van , under a tree that whipped me across my shoulder , through the parking lot to where Brian stepped back out of his car to take the crate , and then I slipped into the back seat of the third car that Hannah was driving . Brian 's house is a huge wood - shingled ancient monstrosity : beautiful , rustic , elegant , simple , surrounded by green with sheep out back .

Answer the following question: Why is Brian eager to leave ?
The situation is worsening .
