Concept:The dominant attitude is the poet's overall emotional tone toward the subject of the poem.
Explanation:The poet complains that a bedbug, which he calls an "awful parasite," disturbs his sleep by sucking his blood at night.
Yet he does not remain angry or bitter throughout the poem.
He exclaims, "Clever thou art, tiny creature," and adds that he can never catch it because it visits only when he is fast asleep.
He also observes, "'Tis so strange," that the bed appears completely clear of the insect before twilight.
His repeated use of the words "wonder" and "strange" shows surprise and curiosity about the bedbug's clever behaviour.
There is no pity, regret, or careless indifference in his tone.
Thus, the feeling that dominates the whole poem is amazement.
