Easy to open packs make me angry- they are NOT easy to open! For who are they easy to open? Engineers? Scientists? Once I have got over my anger, I start to feel inadequate. If they were invented for the general public. If Mr. of Ms. Normal can open one of these packs without breaking out in a sweat or pulling a muscle. If they can end up with the pack still in one piece and not hacked to death by teeth, forks and other such implements...what is wrong with me?! Do I have a below average I.Q? Am I physically challenged in any way that prevents me from mastering this skill. Worrying!
