She was  blowing her nose
On  phone, not from a cold,
While talking of this and that ,
Of her granddaughter, a girl
In pigtails, on way to school.

She was not talking of her son 
Or of his late ghost in the hall .
When the  girl  goes to school
She makes sounds in the hall
Enough to scare away a ghost.
Nose blowing might shoo it off.
