A Knot - A Dilemma

She burnt the candle the whole night thinking about the knot. Not very sure whether to undo the knot or to tighten it up. The leftover wax sparkled her eyes and triggered her mind. She quickly got up, freshened herself and walked towards the front door. She had just turned the knob of the door when her little one tugged her saree. She turned back just to find the twinkling eyes with a question- " Mumma, I ? and all the courage that she had gathered shattered in a fraction of second. Her son clung to her knees with an innocent smile. His Mumma broke the silence and unknowingly tears rolled down her cheeks. Did she stand near the open door in dilemma whether to untie the knot or to tighten it up?
