Stoic...Stolid...Stony

What do you say...
if your head is full of dirt?
You can't say nuttin...
cuz you're an introvert.

What do you say...
if your head is full of plant?
"I won't get a haircut...
I CAN'T! I CAN'T!"

What do you say...
if your head is full of leaves?
"This isn't what I had in mind...
when I said I'd get a weave!"

What do you say...
if your head is full of peat?
You can't even really think...
cuz your head is made of concrete.

What do you say...
if you can never crack a smile?
You learn how to keep a straight face...
and try not to act infantile.
