When I was about four or five years old my next-door neighbor accidentally slammed my finger in her door. She felt soooooo horribly about it and kept apologising to me over and over.
Not long after the incident, she had an adorable baby girl. I thought that her having the baby happened because she had slammed my finger into her door, and that was her ultimate apology.
To this day, a small part of me still believes that.
