Did you ever sleep on a bunk bed?  

I did the same thing, my brother and i shared a room until I was 7. I was on the top.

I used to sleep in a bunk bed before I left home. I used to share it with my sister. When the bunk bed first came home, we used to fight all the time to sleep on the top.But since I was 7 years older than she is, my parents would let me sleep on the top. But later when we grew older, I preferred sleeping below 'coz it was easier for me to get in and out of bed when I wanted to without disturbing her too much and it also made her happy. So, in the end, both of us had our way.

top is safer
