A young lady had her window (not MS!!! - R.P.) broken. She calls for a repairman. Next day a knock comes from the door.
"Who is this?" she asks,
"The repairman" is the answer.
She lets him in, then shows him what to do and goes to her own business. Five minutes later another knock comes from the door.
"Who is this?" she asks,
"The repairman" is the answer.
"But we already got one here," she replies..
"Sorry, Lady, I fell out."
