Which of the poems beyond Sonnet 43 is a sonnet?

Do you know what a "final couplet" is ? It's the last two lines of the poem. You would have saved yourself much time and trouble by simply finding a copy of the poem (it's readily available on the internet) and looking for the last two lines. The last two lines of Sonnet XLIII are "All days are nights to see till I see thee/ And nights bright days when dreams do show thee me."
