I agree. It is a nice idea and I'd like to think they are there, even if not for me then for my kids.
Interesting idea, if not purely subject to opinion, but I had a stange dream that lends to this topic not to long ago....if I may:
I was running through an airport trying to stop a plane that(for some unexplained reason) I knew was going to crash or explode, upon arriving at the security gate I was stopped(of course), and while I was arguing with the guards there I happened to look to my left and noticed a little girl sitting down looking at me. She had very large brown eyes and a bit of a dark complexion with dark shoulder-length hair.......she was the only thing about the dream that I can say I recall vividly, she might have been 5-7 years old(sitting down it was hard to tell more accurately). As I stared at her she smiled and said "don't worry, there watching over you.....the little girls....two of them....they will protect you." The next thing I know I am in an elevator, and when the elevator door opens I am running toward the airplane, when I get a little closer the airplane explodes. I somehow get the feeling that for whatever reason that I was chasing that plane that I had accomplished my mission and that nobody was aboard..........but the little girl and her "message" is what irked me the most. I had a sister that died at birth....maybe she is one of the "little girls" that is watching over me.....but the other....I have no clue.......I just don't know.
Now does this mean I have a guardian/guardians angel? or am I just one hell of a vivid dreamer? again, purely subject to personal opinion, given that there is no proof one way or the other....but if I said that this dream diddn't irk me just a bit...I would be lying.
