Inspired by the episode Party of One.
Pinkie has always had some deep insecurities in the back of her mind. Whether it's about her friends, her husband, or her own kid. For some reason, deep down, she's terrified that every pony around her is going to leave her. One day, these thoughts come full force to the front of her mind, and she's too weak to push them away. In this sorrowful state, Cheese Sandwich pays his loving wife a visit and they talk things out.
For the first time in a long time, Pinkie gives in, and stops being the Spirit of Laughter for a change.
