I flew cross country - yes, over the Christmas holidays. There's not much more excitement than boarding a plane at 5:30 a.m. (I am NOT a morning person...the skycap had to ask me 3 different times where I was going before I correctly answered), stuffing yourself and your bags into a tiny seat next to people fighting you for the armrests, then being told you're heading back to the gate due to electrical problems...just after you took the meds your doctor gave you that would just barely, maybe, last long enough to keep your eardrums from shattering by the time you landed two planes later (because "you REALLY shouldn't be flying"). But wait, there's more!
Securely wedged among sleep deprived passengers, you are suddenly grateful for your recent sleep deprivation due to night time hot flashes (yes, much too young for that, and no, they are not like quick trips to the tropics) because you're not feeling tired. In fact, you're almost energized. You're feeling alive and upbeat...and like it might be time for a bathroom break...except the guy on the aisle is sound asleep and sprawled across every inch he has and much of yours...including the armrest.
In desperation, you wonder how good those throw-up bags are...then remember that at least you'll be able to use this in a novel...if you don't lose the use of your right arm from lack of armrest space. :)
