Watch the clouds when you are high. [=

Stars, definetely. I love the serene night sky,the twinkling stars..

I love the stars because they always bring back great memories :)

I cant pick. I love doing both.

I would watch clouds

Stars. I love how they make me feel small and insignificant, but still important enough to be loved, powerful enough to deal with life, and strong enough to keep going =)
