I will assume you want a public-interest column (opinion/reporting) exploring connections among: the phrase "sexmex" (possibly a band or term), dates "21 12 14" (likely Dec 21, 2014), Kourtney Love (musician Courtney Love?) and a "depressed teacher" linked to those elements. I'll produce a concise, polished column suitable for publication that treats individuals respectfully and avoids unverified allegations.
