Sunny day - potential tra- ge- day ?

 Last weekend during a nice sunny day out at a tourist attraction a disturbing potential accident was averted by only seconds, and it happened right next to me as I was relaxed and in a day dream.

The problem was that a couple with two toddlers took their eye off one of them and during those seconds he  managed to climb up a picnic seat and bench, and then on to the top of a wall. The horrifying thing was that on the other side of the wall was a 5 meter drop onto some stone flags. Only the parents frantic calls made him freeze and not crawl further off the edge. 

Now the problem I have here is that I was leaning on the wall in a daze looking at the view and the child was literally within touching distance. As a parent I felt shocked I had not been aware of the danger he was in. I then went on to imagine the scene if he had fallen and the effect it would have had on me.

The problem is, and this has happened several times to me personally is that even as you are relaxed and happy a fatal situation can suddenly erupt. The last time this happened was the run away tractor on a scenic summer nights drive. There is no escaping the fact that these instances keep happening but luckily by some miracle they are averted. Some have suggested it is good that these instances are averted as though a " guardian angel " is watching over me. He or she must be very busy then. Un- naturally so. 

Could you imagine the affect on my mental health if this situation had been fatal ? I need an outlook or philosophy to settle me and make some sense of this constant peril that seems to rear up randomly at any moment. And at what point do you say to yourself " this is getting out of hand ? ". And is it normal, and do other people experience this but just say nothing ? And why do people never share such instances ? Are they scared too ?

I often smile wryly to myself when I hear emergency sirens on a beautiful summers day. Despite the seemingly perfect  idyllic day some one, somewhere is having a very bad one.
