Love for Bolster

Ever since I was a kid, I always sleep with a bolster.
When I live near college, I always bring my bolster every time.
When I study in Beijing, and looking for blanket, I find a place sell bolster and I bought one right away.
When I move to Shanghai, my bolster come together with me.
I need them to sleep, they're essential in my sleeping habit.
And I'm not planning to stop this habit :)
