Haakon is learning how to rig the pilot during packing, by the end of the day he was due for the exam. Not rigging the pilot properly can mean the worst malfunction ever, so paying attention to detail is crucial.
Packing is hard work when you're a beginner - first of all you're dead worried about the lines not being perfectly stretched, then you loose count of the a/b/c/d lines when folding them into the canopy. Not to mention getting the canopy into the bag, lines still neat and firm. However, after a while you get the hang of it and 45 minutes turns to 15 minutes.
For the rest of us whom still think packing is hard work, God sent us professional packers.
