Case File #006: The Grocery Bag Carrying Threshold
Share
CASE SUMMARY
Dad Lab researchers have identified a peculiar paternal resistance to making more than one trip when unloading groceries from a vehicle.
Regardless of the number of bags, their combined weight, or the structural integrity of the plastic handles involved, Dad will attempt to transport the entire load simultaneously.
Researchers have yet to determine why a second trip is considered unacceptable.
Dad simply knows that it is.
THE OBSERVATION
During routine testing, the subject arrived home with eleven grocery bags in the vehicle.
Researchers expected multiple trips.
The subject opened the rear hatch and began systematically attaching grocery bags to both hands, wrists, and forearms.
One bag contained a gallon of milk.
Another contained several canned goods.
The subject continued loading.
Researchers suggested:
"You could just make two trips."
The subject stopped.
He looked directly at the researcher.
No verbal response was recorded.
Loading resumed.
RESEARCH QUESTION
Why won't Dad make a second trip?
Researchers identified several possible explanations:
- Increased unloading efficiency
- A desire to minimize walking distance
- Competitive grocery transportation instincts
- An irrational distrust of unattended groceries
- Paternal pride
- Two trips are for quitters
TESTING PROCEDURE
Researchers conducted a series of controlled grocery-unloading trials.
With four bags, the subject demonstrated no difficulty.
Six bags required the use of both wrists.
At eight bags, researchers observed significant finger compression.
At ten bags, circulation appeared questionable.
The subject continued.
During the final trial, researchers added a twelve-pack of soda and a large package of paper towels.
The subject successfully lifted the entire load.
Approximately halfway to the house, one bag began slipping from his left hand.
Researchers offered assistance.
The subject responded:
"I got it."
The bag continued slipping.
The subject did not, technically, have it.
FINDINGS
Evidence suggests that Dad's maximum grocery-carrying capacity is not determined by strength, comfort, or conventional physics.
It is determined by the number of trips Dad has decided to make.
Researchers have classified this phenomenon as Single-Trip Load Determination, or STLD.
The number of grocery bags that can be carried simultaneously appears to increase when someone suggests making a second trip.
Researchers believe this may be the first documented example of spite-based load capacity.
Further study is required.
PROF. I. ROLL'S CONCLUSION
After extensive analysis, the Dad Lab has determined that carrying groceries is not simply a household chore.
It is a challenge.
The objective is clear:
One vehicle.
One Dad.
One trip.
Researchers strongly recommend opening the door for him.
His hands are currently unavailable.
