As Wendy pointed out, her support system at home needed to go to work and she was left with the snow.  While the family owns a small plowing machine it doesn't get the job done and by the time they call a guy to come plow the driveway,there is usually too much snow for the truck to make the hill.  This is where I would suggest considering the time/value of hiring a plow to come several times to plow out the driveway.

With anything in our life, our time has a value.  For those of us who are self-employed every hour of our time can be broken down to an hourly rate.  Even if you are not self-employed you can still associate a value to your time.  Wendy needs to figure out what her hourly rate would be.  If 10 hours in the driveway takes her away from 10 hours of working and producing income, she needs to evaluate if hiring a plow to come several times to clear her driveway is actually a cost-savings.  She might want to consider if buying snow blower would be a more effective tool to tackle her driveway.

If you associate the time plus the frustration and emotional toll spending time shoveling the driveway for an entire day, there is also a value.  Wendy needs to evaluate her budget, her workload and her emotional needs to come to a decision that can make her snow days a little more relaxing, productive and less stressful.
