OK, picture the scene...
Man wakes up out of bed, scratches hinself (as all men do) and then begins a very slow and arduous process of determining whether he will brave the elements and cycle into his work this morning. Having made initial investigations (ie looked out of the window and seen the heavy rain, then verified exactly what he had seen by checking
Metcheck online), he proceeds to dress in the appropriate cycling atire and then help the rest of the family get themselves ready for their early departure. Throughout this process, internal discussions are taking place within this man's head, the classic 'will I, won't I' type of discussions that generally only server to frustrate people.
With the family safely sent on their way, these internal discussion are soon externalised with self-directed mutterings and curses. Eventually a decision is reached, the pannier bag is packed and a calm descends upon the man as he slowly accepts quite how wet it is outside and therefore accepts quite how wet he may get on the journey.
The final layer of waterproof clothing is pulled on. The winter gloves, the bike lights and the odometer are all picked up from the kitchen counter. Confidence and anticipation is at an all time high, the man is actually looking forward to making this journey now. The pannier bag is picked up, house keys are searched for and located and the man strides out into the dark rain and locks the house behind him.
A short stride finds him opening the shed door and carefully pulling out his beloved steed, the street lights offering just enough light to complete the manouver.
The bike lights are slotted into place, the pannier bag clipped onto the frame, the man lifts his leg over the steel frame and then....
....well then he looks down and starts swearing at the top of his voice. The back tyre is as flat as a pancake and its too late to change it! The man has to throw the bike back into the shed, stomp angrily back up to the house and get changed in the kitchen before dashing out to catch the train.
moral: Always, always, always check your bike the night before you intend to use it.
