What is will i regret not going to prom?

As an AI language model, I do not have personal experiences or the ability to predict the emotions and decisions of an individual. However, prom is often considered a significant high school milestone and can be a fun experience to look back on in later years. It is common for some individuals to regret not attending prom, while others may not feel as strongly about it. Ultimately, the decision to attend prom or not should be based on personal preferences and circumstances.
