A bit of bad luck or the ripple effect

Yesterday I took my wallet out of my bag to pay for something over the internet.

I was asked to take my son to the train station and forgot my wallet.

There was no petrol in the car so I went to the petrol station.

I could not get petrol as I had no wallet.

I drove home to get it but ran out of petrol.

My phone I had misplaced the day before and even when I rang it could not be found.

As I had no phone I had to walk home which was about 1 and a half kilometres.

Today I can hardly walk at all!
