Shortly after we were married, my wife and I sat down in the living room to put together the gas grill her coworkers had given us as a wedding gift. Now, as you may know, anytime the words "some assembly required" are uttered, the possibility for massive frustration lurks nearby. Pieces don't fit like they're supposed to. The directions are poorly written and don't make sense. You have what appear to be important pieces leftover. Yet, we worked well as a team, and haven't yet blown up the house when we fire up the grill. So, which couple will win this battle to assemble a piece of IKEA furniture first: The couple who's been married 10 years, or the couple who's just met?
