Two story house

A man appears before a judge one day, asking for a divorce.
The judge quietly reviews some papers and then says,
"Please tell me why you are seeking a divorce."

"Because," the man says,"I live in a two-story house."

The Judge replies, "What kind of a reason is that?
What is the big deal about a two-story house?"

The man answers, "Well Judge, one story is 'I have a headache' 
and the other story is 'It's that time of the month.'
