Yes, by all means, every reationship is ready for marriage! And there are no people whose situations might be harmed by civil marriage.

Come on. What if they're still working through an issue or two? What if one of them is dependent on social security (which means they'd lose it if they got legally married)? What if they're politically opposed to marriage? Nothing was said on any of these issues, so why don't we pretend to consider them adults that know what's best for them right now?
