Read the following poem and answer the question that follows.

"when i was one-and-twenty," by a. e. housman

when i was one-and-twenty
i heard a wise man say,
'give crowns and pound and guineas
but not your heart away;

give pearls away and rubies
but keep your fancy free.'
but i was one-and twenty,
no use to talk to me.

when i was one-and-twenty
i heard him say again,
'the heart out of the bosom
was never given in vain;
'tis paid with sighs a plenty
and sold for endless rue.'
and i am two-and-twenty,
and oh, 'tis true, 'tis true.

what connotation does the poet use for the word in bold?

happiness and true love
confusion and fear
anger and a destroyed friendship
sadness and a broken heart

(sighs is bolded)
