Yesterday, i met sudden guest in my flat on the East of the Rivet Town when reading by the window.
i suddenly felt someone’s presense behind me and i found a young petite woman whom i had never met, standing without any words at the center of my room, as i turned back.
when on the earth did she enter the room?
then i noticed that i had not worn the mask. i felt angry at that unwelcome guest.
'why are you here?' i said and stepped back at the room past her.
i put on my mask.
'Please forgive me, sir..' that little lady said and left silently while i had been just gazing at the fireplace.
i went to the dinning room and played the piano.
