The day starts with an early call.
You trust the innocent promise that this early awakening advertises to your mind. You go on to spend the morning ambushed by your own weakness for a sheltered outing, and you hence lay yourself bare. Don't forget, not denuding yourself was not ever an option when on an outing; the outing itself is the act of stripping yourself to the corrosive sway of elements.
The unrequited offer for a seat would go on to nab your peace of mind later, and force you hostage to the need to compartmentalize. Although well compartmentalised at the time of first reckoning, it may have gone on to spread its shadow over your skeletal membranes nevertheless, over the course of the afternoon.
Parental exuberance too may have curdled the mixture a tad, it is smelt.
The other contaminant possible as a suspect is the parting wave. Earlier instances of this conciliatory wave have produced bouts of atmospheric pressure similar to the one being felt now.
Then some self-identifying reading leads to the promise which the day proffered your way in the morning. The sight of your mould in the writing relieves and elevates your mental fortitude.
