on relatives

had an interesting conversation today. ofc half of it was said jokingly

we've discussed who can be considered a relative, and my opponent said that only a person related by blood is considered a relative.
i indicated that by this logic children would be considered relatives, while a husband wouldn't.
my opponent said, well, then husband is considered a relative too, but only he and people connected by blood.
then i asked what if one had several husbands?
it appears that the one you love the most is considered a relative :)

such a relative term it is, 'relatives' :)
