I can sleep everywhere

Partly, I wanna say sorry to myself of not sleeping in a good time, don't have a good sleeping Schedule. I always think when I walking in the street, can I just sleep on the street? My answer is always a NO !

But I wanna make a work or photos book (whatever) about " I can sleep everywhere"

after I sleep everywhere, I found that I regret on thinking about I can sleep everywhere, its dirty and I need a pillow, otherwise its not comfortable, I will try to bring a pillow next time.
