Just remember that you cannot blame Murphy's Law for everything that goes wrong, if the hot water runs out while you're having a shower, it's probably because the hit water heater needs to be fixed , if your car breaks down on the way to a job interview, it is probably because you did not have the vehicle serviced or repaired ,and if you lose all your files on the computer , it is not bad luck - it is your fault for not doing a backup of your files.
