I walk, but have no legs.
I sleep, but never dream.
You can rock me in a cradle, but I am not a baby.
I can go around the world faster than you can cross a room.
We are often dangerous
But to some we are fun
To others, we are frightening
Causing them to run
We come together
Though we seem apart
You see me and you hear my brother
Who ofttimes makes little ones run to their mothers,
I am bright and my brother is loud
And it may seem that we come from a cloud,
