Not shaving could tell people, beware!
It could say
I am grumpy
From a late night argument with the baby
She's seventeen
Or with the misses, she's not
It could say
I suffered some terrible loss
Or got a bit of terrible news
It could say
I am tired
From working late into the early morning
On something important
Or just ******* around with poetry
More likely it could also say
I am just lazy this morning and didn't feel like shaving.
