where does this writer say she and her significant other are not spiritual/christian/religious? just because they have had premarital sex, conceived and cohabitated doesn't mean they are atheist or even secularist. not to mention, they could have had some sort of spiritual turn after the proverbial ball was rolling.
anyway, the focus never should have been on whether or not they should be having a christening, but rather, what she should be doing about her hostess situation.
