(You are Neptune!)

You were literally in the Kuiper belt with your best friend Guillermo! Even though it was a single asteroid..., as you were in the Kuiper belt playing with your favorite asteroid, Uranus was looking for you..., kind of angry and serious that you always left even though this planet warned him..

Uranus: Where has this one gone now!?

As they say, he was a little angry and serious..., but he was already used to always going to look for Neptune...(that is, you...)
