Blink of an Eye

Alex was helping his father with hauling the ingredients into the truck. Neither he nor his Uncle was strong enough to do what his father was doing. 

Alex's father was basically grabbing two packages at once and lifting them without any struggle. Alex sighed as he saw that. His father really was very strong.

"God, your father scares me sometimes," his Uncle said with a chuckle. 

"Scares?" Alex asked with a hint of confusion. 

"Haha, when your aunt was studying at the university and we got together, she brought me back to her house to meet with her brother and your late grandparents. At that time, when I saw a hunky bodybuilder who threatened to beat me if I ever hurt his sister, I was really scared." 

"I sometimes wonder if I would've really ended up with your aunt had your father not threatened me," his Uncle said while laughing to himself. 

"How many times are you going to say you are afraid of me, rob?" Alex's father asked.
