After a stressful night,
I retired for the bed.
but I couldn't sleep.
I felt uneasy.
So I barged into my sister's room.
She woke up abruptly.
"What's the matter?" she asked, trying to calm me down.
I shushed her and told her to follow me to her room's closed window.
There we listened.
The sound of the footsteps can be heard.
With my sister holding on to a pen knife,
we took a peek through the window.
So, What was awake at 3 am?
