Sometimes I've seen HIm

This poem was for English class last year:
Sometimes He's not in that empty space. Sometimes he fills it.
Sometimes he's a total stranger. Sometimes i know him like a good friend
I've seen him down on the ground, I've seen him crazy with rage
but
when i see his true bright smile
All the angles of heaven sing
I've seen him running as fast as he can
 I've seen him slow as a snail
Sometimes he is quiet as death, Sometimes he can't stop laughing.
Any way he looks the same.
my perfect angel
