Butterfly effect

Today, I want to talk about butterfly effect of mine.:)I've had a foul morning,I go to work by ride bike this morning .I bought a carton of cigarrete on the road then I go on,but suddenly it's rain,and it's very heavy,I have to seek shelter.after a while it's stop,but I'm soaked through and chiled,what a pain!
In this time I think this is the butterfly effect,you know If don't smoking,then I don't need to bought cigarette,and if I don't bought it,I'll not took a very roundabout way,and if I don't tookk a very roundabout way,I'll go to the office in time.then I won't be soaked wet.Hmmm....
