Mahdi struts the halls on a straight path
His Arab face snugly tucked behind his mask
He is the tech who is a strict adherent of the rules,
Aptly named
Tall and skinny

Not a favorite of the patients, largely unnoticed, works overnights
Won't always give you a snack
But he was a favorite of mine.

Mahdi walks a straight path and I think it is just ... fine!
