The blue scooter

"What on earth is this?" mumbled Margaret, as she peeped out of the Window. She turned and shouted the question to her husband in the toilet.
 
Mathew was rushing for a busy day. He was a real estate agent and it wasn't the best of the times. Last thing he needed was a situation.

   "It’s a blue scooter. I saw it parked at the street across. What's wrong with that?" His question betrayed his irritation.
 
Margaret did not reply. Mathew couldn’t see her ashen face. Neither could he see the metal tentacles moving at unearthly speed towards Margaret’s throat.
