Mark dropped the heavy grocery bags onto the hardwood entryway, letting them fall with a thud.
"Mom! What happened, what happened?" Mark asked, looking rapidly back and forth between the two women.
Evelyn immediately put on a weak, pathetic expression and clutched her own chest dramatically.
"Oh Mark, your wife has completely lost her mind! She just shouted at me for no reason!"
Evelyn began to fake tears, trying desperately to play the victim before Mark could ask questions.
She claimed that she had accidentally bumped into the crib while trying to help out around house.
Sarah held her baby close, glaring at Evelyn with total disgust at her continuous cheap lies.
Before Sarah could speak up to defend herself, little Lily stepped forward from the dining corner.
The seven year old girl raised her bright smartphone screen high for her father to see clearly.
"Dad, Grandma didn't know I was recording," Lily said in a firm, confident voice.
Evelyn's eyes widened in pure horror as she realized her cruel secret was caught on video.
Mark took the smartphone from his daughter's trembling hands and hit the clear play button.
The high definition video showed Evelyn intentionally dropping the innocent baby right onto the carpet floor.
It also clearly captured her mocking words and her smug smile right after the fall occurred.
Mark's face flushed deep red with instant rage as the video finished playing on the screen.
He looked up at his mother, feeling a profound sense of betrayal deep inside his heart.
He could not believe that the woman who raised him could act so heartlessly toward his son.
"How could you do something so terrible to my child?" Mark whispered in total disbelief.
Evelyn began to stammer, trying to find another excuse to cover up her despicable actions.
Mark stepped forward aggressively, his hands trembling with uncontrollable fury as he stared at her.
He realized that his mother had been trying to destroy his happy marriage from the start.
