Guardian Angels?

Do you believe in guardian angels?
My mother, a VERY religious women who likely would have become a sister had she not become a mother, believes we have guardian angels. Then again she believes all things Catholic.
From time to time in my life I have certainly had incidents where someone or something was looking out for me.
I'm a smart guy, just not all the time - consider the number of times I stuck my hand in: a fan (twice), a mixer (when I was 12) and a water pump (when I was 4).
Once out hunting with my friends (we were in high school) one of my companions was shooting at a squirrel. The squirrel was running left to right, with my friend - flinging led from a 20-gauge shotgun - in hot pursuit. As the squirrel moved to the side, my friend and his shotgun barrel followed. My friend wasn't paying attention to anything other than squirrel - until he shot the hat off one of the other members of our hunting party.
We were damn lucky that day.
My freshman year of high school, I was walking with friends, turned around talking to them, when I stepped out in front of a car. The left-front wheel of the vehicle ran over the tip of my foot and bookbag broke the mirror on the passenger side door. I was unscathed.
I was never injured in seven years as a river guide. And I never injured anyone either. Even that one time when we were on a river we never should have been one at unsafe water level and I had a boatload of fat people and kids. Single scariest day of my life as a guide.
Then there was the time in college when a bunch of us (15 guys) were in the back of a V-6 Ford Ranger and the driver (doing about 20 mph) pulled into Interstate traffic in front a roaring semi, doing about 65 mph. The truck almost wrecked to avoid hitting us and how none us got hurt that day - I'll never know.
Then there was the day I try not to think about - what could have happened.
In elementary school (I was in fifth or sixth grade) one morning, a van with two men pulled into the parking lot. They pulled up to the edge of the lot. I don't remember if they pulled up beside me, or if I walked over to them. But I do remember they asked for directions to Midland Trail, which was about 20 miles away. It struck me as odd from the minute it started, but I stood there a few feet from the driver's side door - a fifth grade kid giving two grown men directions. There were other kids and probably a teacher or two on the playground but none were close to me. These guys could have grabbed me and gone and I might have become Fayette County's version of Adam Walsh.
At any rate ever since that day - ever since those guys left the parking lot - I always thought they were up to something sinister. And I came within an Angel's breath of becoming part of it.
I don't know if it was due to Angels, a charmed life or just dumb luck, but here I stand.
