Ah, Search Terms, how you beguile me. Some days it's all "best-ever cream cheese frosting" and "ben and birdy" and "yoni crack martini glass" and "nursing until your boobs fall off."
And then some days it's this. Let's see. Am I and my expet on marriage? Do you mean like *on* marriage--like, we're *on* it, marriage? Me and my expet. Expet, like exparrot in Mony Python? That might be our cat Tiny, I suppose. So are you wondering if I've been betrothed to the groomish ghost of my dead cat? All I can say is, if I were, it would only be for the health insurance.
But if you're asking if I'm an expert on marriage because you've been assigned a response paper to my essay, "I Do. Not."--well, all I can say, my poor Comp 101 friend, is: you'd better proof-read it.
