Some places preps are just for comfort:

Leaving some big events like music events and sports, there is a considerable wait time to get out. I find expecting this makes the wait much easier.

One annual event I like is crowded and the waiting time in your car often exceeds 90 minutes - double that at closing or in bad weather. So I pack some water and snacks and wait it out in my air conditioned car.

Well, if there is an emergent need, the goal is to ensure the time is spent productively. To me, that means introspective time.

I may pull out a ukelele or half-size guitar. Always good to practice, and sing a bit, and work out a difficult chord transition. Have to be careful, though: it seems females cannot resist musicians, and I am spoken for. Though not immune to the flattery of fine ladies embracing my music.

More likely, I will indulge in old literature on a beater tablet. Arthur Conan Doyle, Dickens, all manner of cultural treasures from gutenberg.org .

I will definitely not be browsing news sites to feed the latest click bait of celebrities or politicians acting like spoiled children and/or shameless media-hogs.
