Sometimes being distractible has its disadvantages. Say, for example, that you're at your second job and you meet the teacher from the class before you - a shaggy-haired (male) hipster in a long paisley print skirt. And you're trying to concentrate on what he's saying about 18th century German philosophy and manga, but all you can really think about is what a *fantastic* addition he'd make to your trivia team, and how you'd kind of like a tailored shirt made out of the paisley print skirt fabric. And you're wishing you could bring that up without 1.) seeming totally awkward, and 2.) making the guy think you're hitting on him, because he strikes you as a bit socially awkward himself, and you're afraid that all the resulting awkwardness would result in a rip in the time-space continuum, and you really don't want to get sucked into some sort of alternate universe, because who would feed your dog?
That is why it is better to be a person who can focus, Internets. If I could actually focus, *I* might be a good addition to my trivia team. Oh well.
