When I was 5... my best friend's grandfather was visiting her. Knowing this, I begged my parents to let me go anyway and visit my friend. Knocking on the door, my friend's mom answered the door. Grabbing me the arms, she started shaking me pretty bad and yelled at me saying that I couldn't visit my friend. I walked home in tears, and haven't told anyone about that. Still haunts me to this day.
