A rhetorical question for you all

Life deals its blows
In varied strikes
Events of my life
Are no different

The moments arrive
Often too quick
I cry at the event
Of thunderous emotion

Then the well dries
And the tears fail
To release my heart
From an endless pain

A strange thing occurs
In my lonely travels
An unexpected release
Found in the air

It seems the flood
Of hidden tears
Prefers the higher stage
To let loose my heart

So in my airy travels
My eyes well up
And the calm bursts
Into a salty flow

So I pose a question
TO those that hear
A teary question
That I proclaim

And here it is
That simple question
That I ask of you
"Why do I only cry on airplanes?"
