Guy friends draw parallels between adopting daughter and son (9)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

COMPARE (draw parallels between) containing [adopting] D (daughter), then S (son). Although the answer was write-in I puzzled a while when preparing the blog over the presence of ‘guy’. A little research reveals that a ‘compadre’ is specifically a male friend, and the female equivalent is ‘comadre’. One lives and learns! Amusing, given that in English the term ‘guys’ no longer necessarily makes that distinction.
