Signs...or maybe not

Sometimes I wonder about things that happen to me.  I wonder whether they are just random occurrences or maybe, just maybe, if I could look at my life in it's entirety it would look like a treasure map with the landmarks of my life leading me towards something...something I'm supposed to do.  Today while I was riding my bike I saw a mass of black fur amongst the green of the trail.  It was a small black cat with foggy green eyes, we sized each other up, letting our eyes meet to evaluate each other.  I rode on, letting my eyes steal one last glance behind my back at the cat who slowly stalked across the path.  As I kept riding I saw a beautiful red winged blackbird sitting by the side of the trail. I acknowledged it but kept riding.  All of a sudden, I heard a death caw from a above me and felt wings beating down ferociously from the sky.  I was no joke attacked by a red winged blackbird.  When does that ever happen? It was terrifying and hilarious in it's craziness.  Things like that make me wonder,  is it a sign or is it my acknowledgement of the event as out of the ordinary that makes it a sign to me?  After all, aren't we the only ones who have the power to give our lives meaning?
