<span>The following are the lines 16–18 (Act 2, scene 1), in which Macbeth tells Banquo that he and his wife couldn’t entertain the king as they would have liked.
</span>
Being unprepared,
Our will became the servant to defect,
Which else should free have wrought
= these lines are ironic because the wife of Baquo liked to entertain the king but she can't because she is not prepared. Her will to entertain may cause a mistake because she was not prepared what should be carefully done.
One great example of suspense in the Hobbit is when Bilbo is in Smaug's smoky, gold encrusted lair, trying to find the sparkling cup, without awakening the dragon. A few times, we see the dragon release a puff of smoke, or stir, and Bilbo stops abruptly, than tiptoes forward quietly. There is so much suspense here while we await his fate!!
