I’m one of most forgetful people ever and if I haven’t written something down then it is 100% erased from my mind. I always have to make a checklist if I’m going somewhere or otherwise I’ll arrive, with half of the items I should’ve packed still at home.
Most places you’re going, whether it’s on holiday, or just a weekend away from home, it tends to be okay if you forget something as there’s shops nearby to grab the essentials. However, when it comes to festivals, you really are screwed. Stuck in a field, in the middle of nowhere, in need of whatever it is you’ve left at home and no way of buying anything.
