Is that pee on the floor?

My 22 month old daughter Henry is potty trained. That being said she had recently decided to exert her independence by going to the potty on her own. Do I love this independence YES as it give me less responsibility in my day or so I thought.
Today as I was in the living room folding laundry, and Henry was in her room playing or so I thought. She decided to go to the bathroom on her own. All the sudden I heard crying, even now after the fact I don't know what the crying was about. I went to check on her and found her in the bathroom with a floor covered in pee. After playing 20 questions with a child who's vocabulary consists of "mama", "dada" and "no" my Detective skills figure out Henry had gone pee by herself and dumped the potty into the toilet - just like mom and dad do. However she missed the toilet in the dumping process and watered the floor with it.
So as I was very happy she exerted her independence I was not happy I had to mop up pee.
The silver lining - H did manage to get her underwear and pants back up properly! That is a first :)
