You decide it is worth losing the suitcase to keep your life and sanity, both of which could be forfeit if you cross that bridge on the bus. You watch from a distance as the bus driver goes accross the acid eaten bridge. You hear the horrible creakings and you see the bridge sway and bend making loud metallic protests. The passenger windows flake with dried ultra hot vomit and they are impossible to see into. But the bus makes it across and you feel a little weak for not rideing across with the others.
