When my aunt was younger she used to pick on her brother who was short, fat and slow. Then she would run off and he couldn’t catch up to her to teach her a lesson. Then the day came that she tried it after he began to grow taller and stronger. But he caught up to her. My grandfather knew my aunt’s character and what she had been doing and just stood by watching. My grandmother saw them fighting and told him to put a stop to it. My grandfather said “Let them go.” That ended my aunt’s shenanigans against my uncle.
