Careful now!
I cautiously stick my big toe into the shower
to test the temperature.
Too cold.
I jerk my faithful harbinger out and
turn the knob counterclockwise
ever so slightly.
The second testing proves only tepid.
I turn it up again and inch my way into the stall,
I unwittingly touch the cold wall
and breathe in sharply.
How long is the lag
between adjusting and results?
The seconds, how they drag
in this temperature precipice.
One would think that
One wrong move will be the death of me.
I step in confidently to embrace the warmth,
“Aaaaarrgghh, turn it down! Turn it down!”

Haha! It’s bad enough in my own familiar one, especially with the weather changing now.
Ahh the joys of temperature control. Amazing how when you are away from your own shower how difficult this can sometimes be! 😃🐻
