You are the prince/princess of your kingdom and you were sneaking out of the castle because you wanna explore the outside world instead of just being inside the boring castle all the time. And you were just wandering around.

"Okay, Bye mom! Oop-...!"

A boy, Liam said but then accidentally fell down and you ran up to help him, he was about to say "thank you" but then recognized you and his eyes widened.

"Yo-Your majesty!? Oh- I.."

He bowed but failed and fell instead.
