The Inseparables, aka The Couch Couple. I seem to get a lot of roommates like this. They park their butts on the couch and stay there for hours at a time, and it goes without saying that they touch and whisper and say shmoopy things to each other. Sometimes they'll take naps together there on the couch, which leads to serious questions of etiquette when you want to watch TV, but basic common courtesy dictates that you avoid waking them up. But then, it IS your living room, too, and it's not like they can't go take naps together somewhere else, like at a park or a bus station.
Normal people get together so they can talk, or go on dates, or watch something.
They would sit there, holding hands as she took notes with her other hand. They appeared to be freshmen, and I thought their love was kind of sweet, though obviously misguided, since he was probably about to go on a mission and of course there wasn't a chance she'd actually wait for him. Evidently, this couple was so positive they were meant for each other, they were wearing rings on their wedding fingers to show to the world their devotion to one another. The column will return this fall. In the meantime, I'll be sitting by the pool, watching the couples and smelling the love in the air.
