Here are 5 reasons that this poem qualifies as a Sonnet.
1.The poem has couplets
2.the lines rhyme in a certain order
3.the last couplet is the only rhyming couplet
4.it contains 14 lines
5.the last couplet is the main idea or the thesis
I like this poem becuase it has humor and some liveliness in the rhyming but it also has some seriousness in the fact that thye story is about a woman with no one to love.
