Dear fellow reader with too much time,
@someunregpunk,
I appreciate your counter-argument but I am standing by my previous statement. I have consulted with the omniscient Google-sensei, and his answer states that soup is liquid food made by boiling. Thus, unless you have a peculiar liking to hot-mushy-baby-food-like cereal, cereal is not soup.
Another question I have stumbled on that might trigger some late night ponderings is:
Is toothpaste a liquid or a solid? 🤔
