What is the affect of couplets in "to my dear loving husband" and "to the kings most excellent majesty

A couplet is a pair of successive lines of metre in a poem or a song. These lines usually rhyme and share the same metre. In this case, both "To my Dear Loving Husband" and "To the King's Most Excellent Majesty" employ a couplet. This couplet is located at the end of the poems. There are two main reasons why the couplets are used in this way. First, the couplet is meant to provide a sort of "conclusion" or "answer" to the questions posed in the rest of the poem. The second reason is that the couplet is meant to add to the melodic rhythm of the poem by concluding with a rhyme. The effect of this is making the poem more memorable to the reader.

the narrator is saying that the old lady made her feel uncomfortable. you know this because they say "i found that rather irksome", "perhaps it was her being so upright and trim", and "i don't think it was that, because i thought that quaintly pleasant." hope this !
