i think i have a couple. the biggest one being my Dad. he saved my life a few times and always helps me get out of things that i dont think i can do alone. i dont see him. but i feel him. he's always with me. always. i feel him kick my ass when i do something stupid, and i feel him hold my hand and walk through my daily shit life with me.
my personal opinion is that everyone has a guardian angel, or more, whether u believe in it or not...
