why it is...

how come everytime i am broke, the chain on my bike needs readjusting $6.50 the day before the tire goes flat $10 the guy that sells the green vegtables has really good crops that week, tickets for all the good concerts that are sure to sell out by the time you can afford it go on sale and my dirty laundry is piled up like a blockade of sandbags preventing entry into my bedroom a few days before i leave to texas?
