Walking on the ceiling

Today, I was waking up on the ceiling when I heard a "click" sound. 

It all started on the weekends, I found a secret music box that had a picture of a person walking upsides down. "Wow, I wish I could walk upside down like the one in the picture", and that is how it got started.

It was Monday, I started to walk to school, but when I got to the classroom, all the teachers and classmates said that I was walking on the ceiling. I examined the classroom and still did not believe that I was walking on the ceiling. 

First of all, if I were walking on the ceiling, then gravity would not exist, and I would be weightless! If there is no gravity, everything will float, but my classmates said that only I was floating so it does not make sense.

Second of all, if I could walk on the ceiling, what would happen to me if I were outside? Would I float into outer-space, or would I just stay the same? 

But then, I realized that the music box had a picture of a person walking on the ceiling, and that person could be me! After school, I dashed to the music box (I hid it under my stuffed animals) and looked at the person that was in the picture. The upside-down person talked to me. I got scared and (ran away) did not hear what the person said. I only heard a "listen to the m....in the b....." I thought she said, "listen to the music in the box." I tried to open the box, but I could not. 

I found a secret key in the back of the music box (good luck I found it) after A LOT of searching. When I found it, I easily opened the music box, right when I was about to listen to the music, my mom came to my room and handed me a bowl of mangoes. I shivered and said "ok, I-I will eat it, by-by-bye". My mom said, "You talk differently, (sigh) never mind.... Bye!" My mom almost found out that I had a secret that I did not tell her. But now, I have to turn myself right side up. After I listened to the music, I went to school again. This time, nobody told me that I was upside down! What a fun day!
