According to the speakers in the poem ''On the Grasshopper and Cricket'', the sleepy human might mistake the cricket song for what ?

hope or optimism...... it is the sound of hope and a reminder of warmth

Are you sure is that right ? Just asking .

On a lone winter evening, when the frost

Has wrought a silence, from the stove there shrills - this is the cricket

The Cricket's song, in warmth increasing ever - denotes warmth

And seems to one in drowsiness half lost,

The Grasshopper's among some grassy hills. -remembrance of summer

Oh okay Thank you ! (:
