So I was going to write another kitschy column about how I’ve morphed into a frat bro. It was going to be pretty great, too, replete with mid-’90’s hip-hop references and copious use of the phrases “legit,” “bro” and “yo.” But I am experiencing a brief bout of self-righteousness, so please excuse this foray into the semiserious. Don’t worry: Next time I will return to talking about myself.
